When trying to make the hiddev driver issue several Set_Report control
transfers to a custom device with 2.6.13-rc6, only the first transfer in a
row is carried out, while others immediately following it are silently
dropped.
This happens where hid_submit_report() (in hid-core.c) tests for
HID_CTRL_RUNNING, which seems to be still set because the first transfer is
not finished yet.
As a workaround, inserting a delay between the two calls to
ioctl(HIDIOCSREPORT) in userspace "solves" the problem. The
straightforward fix is to add a call to hid_wait_io() to the implementation
of HIDIOCSREPORT (in hiddev.c), just like for HIDIOCGREPORT. Works fine
for me.
Apparently, this issue has some history:

Fixes handling of multi-transaction reports for HID devices. New
function hid_size_buffers() that calculates the longest report
for each endpoint and stores the result in the hid_device object.
These lengths are used to allocate buffers that are large enough
to store any report on the endpoint. For compatibility, the minimum
size for an endpoint buffer set to HID_BUFFER_SIZE rather than the
known optimal case (the longest report length).
It fixes bug #3063 in bugzilla.

This driver is a basic keypress input driver for the Keyspan Digital
Remote with part number UIA-11. Currently there is an older remote with
part number UIA-10 which isn't supported by this driver. Support for
the older UIA-10 could be added but a binary file is required to be
download to the device, and I don't have that file. I also don't have a
UIA-10 device so I wouldn't be able to test any of the changes.

Currently hid-core follows the same code path for input reports
regardless of whether they are a result of interrupt transfers or
control transfers. That leads to interrupt events erroneously being
reported to hiddev for regular control transfers.
Prior to 2.6.12 the problem was mitigated by the fact that
reporting to hiddev is supressed if the field value has not changed,
which is often the case. Said filtering was removed in 2.6.12-rc1 which
means any input reports fetched via control transfers result in hiddev
interrupt events. This behavior can quickly lead to a feedback loop
where a userspace app, in response to interrupt events, issues control
transfers which in turn create more interrupt events.
This patch prevents input reports that arrive via control transfers from
being reported to hiddev as interrupt events.

when stealing code from ati_remote for a GPL-driver of my usbradio (because of
its neat usb int transfers) I found out, that the inbuf is freed twice.
I don't have the ati-remote, so I don't know it is a problem at all, but it
looks strange to me anyway. Also I don't know if it has been fixed already in
newer kernel versions.

This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
