Johannes Weiner 96fe2ab830 HID: fix waitqueue usage in hiddev
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list
to 'empty' but to zero.

prepare_to_wait() will not enqueue the descriptor to the waitqueue and
finish_wait() will do list_del_init() on a list head that contains
NULL pointers, which oopses.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".

The prior code used an unconditional add_to_waitqueue() which didn't
care about the wait descriptor's list head and enqueued the thing
unconditionally.

The new code uses prepare_to_wait() which DOES check the prior list
state, so use DEFINE_WAIT instead.

Johannes Weiner 48e7a3c95c HID: fix incorrect free in hiddev
If hiddev_open() fails, it wrongly frees the shared hiddev structure
kept in hiddev_table instead of the hiddev_list structure allocated
for the opened file descriptor.  Existing references to this structure
will then accessed free memory.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all

Anssi Hannula daedb3d6a9 HID: move tmff and zpff devices from ignore_list to blacklist
The devices handled by hid-tmff and hid-zpff were added in the
hid_ignore_list[] instead of hid_blacklist[] in hid-core.c, thus
disabling them completely.

hid_ignore_list[] causes hid layer to skip the device, while
hid_blacklist[] indicates there is a specific driver in hid bus.

Re-enable the devices by moving them to the correct list.

Michael Tokarev 35cfd1d964 HID: blacklist Powercom USB UPS
For quite some time users with various UPSes from Powercom were forced to play
magic with bind/unbind in /sys in order to be able to see the UPSes.  The
beasts does not work as HID devices, even if claims to do so.  cypress_m8
driver works with the devices instead, creating a normal serial port with which
normal UPS controlling software works.

The manufacturer confirmed the upcoming models with proper HID support will
have different device IDs.  In any way, it's wrong to have two completely
different modules for one device in kernel.

Blacklist the device in HID (add it to hid_ignore_list) to stop this mess,
finally.

Alan Stern 011b15df46 USB: change interface to usb_lock_device_for_reset()
This patch (as1161) changes the interface to
usb_lock_device_for_reset().  The existing interface is apparently not
very clear, judging from the fact that several of its callers don't
use it correctly.  The new interface always returns 0 for success and
it always requires the caller to unlock the device afterward.

The new routine will not return immediately if it is called while the
driver's probe method is running.  Instead it will wait until the
probe is over and the device has been unlocked.  This shouldn't cause
any problems; I don't know of any cases where drivers call
usb_lock_device_for_reset() during probe.

Matt Helsley 25e61613cf HID: add proper support for pensketch 12x9 tablet
The Genius PenSketch 12x9 tablet has a puck (labeled a
"Tablet Mouse") in addition to a pen. Without registering a quirk
the tablet appears to be a single input device that reports the
wrong axis information in /proc/bus/input/devices, and sends
incorrect events (e.g. ABS_Z instead of ABS_Y). This information
confuses the X evdev driver and makes the device impossible to
use.

The quirk fixes events and splits the device into multiple input
event devices so that at least the puck is useful.

Oliver Neukum 079034073f HID: hiddev cleanup -- handle all error conditions properly
This is a cleanup of hiddev and fixes the following issues:

- thread safety by locking in read & ioctl, introducing a per device mutex
- race between ioctl and disconnect, introducing a flag and locking
  in form of a per low level device mutex
- race between open and other methods, making sure only successfully
  opened devices are put on the list, changing order of events
- range checking both upper and lower limits of the minor range
- make sure further calls to open fail for unplugged devices even if
  the device still has opened files
- error checking for low level open
- possible loss of wakeup events, using standard waiting macros
- race in initialisation by moving registration after full initialisation

Kay Sievers 6bbe586fd4 HID: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

This patch (as1146c) makes usbhid automatically call usbhid_set_leds()

In theory this should be perfectly safe.  BIOSes send the LED output
report as part of their normal device initialization, so any keyboard
device supporting the boot protocol has to be able to handle it.

As a side effect, the hid-dell and hid-bright drivers are no longer
needed, and the Logitech keyboard driver can be removed from hid-lg.

Oliver Neukum 7d672cd750 HID: fix locking in hidraw_open()
As open needs to sleep hidraw was wrong to call it with a spinlock held.
Furthermore, open can of course fail which needs to be handled.

Alexey Klimov 6a13378a56 V4L/DVB (9337a): HID: Don't allow KWorld radio fm700 be handled by usb hid drivers
This device is already handled by radio-si470x driver, and we
therefore want usbhid to ignore it.

Al Viro 233e70f422 saner FASYNC handling on file close
As it is, all instances of ->release() for files that have ->fasync()
need to remember to evict file from fasync lists; forgetting that
creates a hole and we actually have a bunch that *does* forget.

So let's keep our lives simple - let __fput() check FASYNC in
file->f_flags and call ->fasync() there if it's been set.  And lose that
crap in ->release() instances - leaving it there is still valid, but we
don't have to bother anymore.
