It appears that when the XO touchpad unit resets from ESD, it sends AA
AA instead of AA 00, the psmouse-base code handles the case of AA 00 by
triggering a serio reconnect for the port, causing a full reprobe of
the device.
Testing with OFW shows that this is likely to solve the problem, so
the attached patch simply expands the existing test to also catch AA AA.

When userspace sets effect->u.rumble.strong_magnitude to 0x8001 or
larger, ml_combine_effects() would always return strong_magnitude
0xffff.
Problem is that 'gain' is passed in as signed integer. Multiplying
magnitude (__u16) with gain (int) causes magnitude read as signed and
results negative value (with magnitude > 0x8000). This signed integer
is then divided and value, still negative, converted to 32bit unsigned
integer. Finally checking combine overflow min(new+old, 0xffff) gives
out 0xffff.
Fix is to simply change 'gain' to unsigned int.

In order to utilize the full power of the new multi-touch devices, a
way to report detailed finger data to user space is needed. This patch
adds a multi-touch (MT) protocol which allows drivers to report details
for an arbitrary number of fingers.
The driver sends a SYN_MT_REPORT event via the input_mt_sync() function
when a complete finger has been reported.
In order to stay compatible with existing applications, the data
reported in a finger packet must not be recognized as single-touch
events. In addition, all finger data must bypass input filtering,
since subsequent events of the same type refer to different fingers.
A set of ABS_MT events with the desired properties are defined. The
events are divided into categories, to allow for partial implementation.
The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked.
If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide
the size of the approaching finger. Anisotropy and direction may be
specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and
ABS_MT_ORIENTATION. Devices with more granular information may specify
general shapes as blobs, i.e., as a sequence of rectangular shapes
grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE
may be used to specify whether the touching tool is a finger or a pen.

Simple input driver support for the events reported by the
MSP430 firmware on the DM355 EVM. Verified using the RC5
remote included with the kit; docs weren't quite right.
Some of the keycode selections might need improvement; they
can be remapped, so there's at least a runtime workaround.
(I also suspect Linux may someday merit more generic support
for RC5 based remote controls.)
These events don't distinguish key press vs release events,
so this reports both and then skips the next event if it's
identical. The RC5 remote codes include a "toggle" bit that
can help detect autorepeated keys; but this driver doesn't
bother with those nuances.
This driver relies on the drivers/mfd/dm355evm_msp.c code
for core features, including sharing I2C access to this
firmware with GPIO, LED, and RTC support.

Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.
We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.
But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.
->read_proc/->write_proc were just fixed to not require ->owner for
protection.
rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.
Removing ->owner will also make PDE smaller.
So, let's nuke it.

* 'bkl-removal' of git://git.lwn.net/linux-2.6:
Rationalize fasync return values
Move FASYNC bit handling to f_op->fasync()
Use f_lock to protect f_flags
Rename struct file->f_ep_lock
Most fasync implementations do something like:
return fasync_helper(...);
But fasync_helper() will return a positive value at times - a feature used
in at least one place. Thus, a number of other drivers do:
err = fasync_helper(...);
if (err < 0)
return err;
return 0;
In the interests of consistency and more concise code, it makes sense to
map positive return values onto zero where ->fasync() is called.

Mikrotik's Routerboard 532 has two builtin buttons, from which one
triggers a hardware reset. The other one is accessible through GPIO
pin 1. Sadly, this pin is being multiplexed with UART0 input, so
enabling it as interrupt source (as implied by the gpio-keys driver)
is not possible unless UART0 has been turned off. The later one though
is a rather bad idea as the Routerboard is an embedded device with
only a single serial port, so it's almost always used as serial
console device.
This patch adds a driver based on INPUT_POLLDEV, which disables the
UART and reconfigures GPIO pin 1 temporarily while reading the button
state. This procedure works fine and has been tested as part of
another, unpublished driver for this device.

On parisc machines, which don't have HIL, removing the hilkbd module
panics the kernel. Fix this by adding proper implementations for the
probe and remove functions to the parisc_driver structure.
A few functions were renamed to clean up the code and make it easier
readable.
Disable the MODULE_DEVICE_TABLE() macro on parisc since the kernel
module autoloader should instead prefer the hp_sdc driver which takes

supporting concurrency (all needed to support the Dreamcast visual

Changes in the bus driver necessitate some changes in the two maple bus
input drivers that are currently in mainline.
As well as supporting block reads and writes this code clean up removes
some poor handling of locks, uses an atomic status variable to serialise
access to devices and more robusly handles the general performance
problems of the bus.

net/can/bcm.c - hence I'm CC-ing the folks responsible for that code.
Furthermore, the hrtimer core now calls callbacks directly with IRQs
disabled in case you try to enqueue an expired timer. If this timer is a
periodic timer (which should use hrtimer_forward() to advance its time)
then it might be possible to end up in an inf. recursive loop due to the
fact that hrtimer_forward() doesn't round up to the next timer
granularity, and therefore keeps on calling the callback - obviously
this needs a fix.
Aside from that, this seems to compile and actually boot on my dual core
test box - although I'm sure there are some bugs in, me not hitting any
makes me certain :-)

ml_ff_playback() uses spin_(un)lock_bh. However this function is
called with interrupts disabled from erase_effect() in
drivers/input/ff-core.c:196.
This is not permitted, and will result in a WARN_ON in the bottom
half handling code. This patch changes this function to just use
spin_lock_irqsave() instead, solving the problem and simplifying
the locking logic.

The usbtouchscreen module implements a driver for the TSC-10 DM USB
touchscreen controllers, but assumes a 2-byte response for the
CMD_RESET and CMD_RATE commands, when they can be only a single byte
when no EEPROM is connected.
The driver worked with an earlier controller revision, but new
revisions of the controller fail.
It seems the problem is that the early controller had the
SEL4/EEPROM-CS pin high, but the new controller has it down, making
the response different.
Without the fix, the controller would answer the single byte 0x06
(ACK), making the init fail with -ENODEV because buf[1] is 0xFF (as
initialized before).
As the single byte is the only thing we need to check it was ok, there
is no need to verify the second byte.
The [0x15 0x01] case is the NAK [0x15] response for when there is no
data in the EEPROM [bit-0 of second byte set], so I let that be, as I
don't have any controller with an EEPROM.
With this patch, both the earlier and latest controller work the same.
Note: This was previously submited as BUG #11961 [1] on the bugzilla
tracker, but rebased to version 2.6.27.4 and with unnecessary comments
and printk's removed.

So let's keep our lives simple - let __fput() check FASYNC in

The appletouch driver has grown up from supporting only a couple of
touchpads into supporting many touchpads, which can have different
number of sensors, different aspect ratios etc.
This patch cleans up the current driver code and makes it easy to
support the features of each different touchpad.
As a side effect, this patch also modifies the 'Y' multiplication factor
of the 'geyser3' and 'geyser4' touchpads (found on Core Duo and Core2
Duo MacBook and MacBook Pro laptops) in order to make the touchpad
output match the aspect ratio of the touchpad (Y factor changed from 43
to 64).

hopping when many fingers are on the trackpad. In addition, a finger
counting method based on pressure information from all fingers is
introduced. Together with a pressure hysteresis window, this yields a
more stable counting of the number of fingers on the trackpad.

The i2c layer got changed while the migor_ts driver was in the input
tree waiting to get merged upstream. Fix current compile issue by using
struct i2c_client member "name" instead of "driver_name". Also, add
id_table to make sure the device gets properly detected.

Support for loadable keymaps. The driver now supports individual
keymaps for each of the five modes (AUX1-AUX4 and PC) of the
remote. To achieve this the keymap scancode is interpreted as a
combination of the mode and actual button scancode. The original
keycode patches were done by Peter Stokes <linux@dadeos.co.uk>
but I modified it quite a lot.

Perform actual driver registration right in gameport_register_driver()
instead of offloading it to kgameportd and return proper error code to
callers if driver registration fails.
Note that driver <-> port matching is still done by kgameportd.

Currently the support for each WM97xx touchscreen model is compiled out
by default, meaning that the default configuration when the driver is
built is for it to support no hardware. This is suboptimal and leads to
problems like distribution kernels shipping a non-functional driver.
Change the default to support all controllers and update the help text
to reflect this.
