HID: Add a new id 0x501a for Genius MousePen i608X

2015-01-16T14:59:31+00:00

commit 2bacedada682d5485424f5227f27a3d5d6eb551c upstream.

New Genius MousePen i608X devices have a new id 0x501a instead of the
old 0x5011 so add a new #define with "_2" appended and change required
places.

The remaining two checkpatch warnings about line length
being over 80 characters are present in the original files too and this
patch was made in the same style (no line break).

Just adding a new id and changing the required places should make the
new device work without any issues according to the bug report in the
following url.

This patch was made according to and fixes:

HID: add battery quirk for USB_DEVICE_ID_APPLE_ALU_WIRELESS_2011_ISO keyboard

2015-01-16T14:59:31+00:00

commit da940db41dcf8c04166f711646df2f35376010aa upstream.

Apple bluetooth wireless keyboard (sold in UK) has always reported zero
for battery strength no matter what condition the batteries are actually
in. With this patch applied (applying same quirk as other Apple
keyboards), the battery strength is now correctly reported.

HID: roccat: potential out of bounds in pyra_sysfs_write_settings()

2015-01-16T14:59:31+00:00

commit 606185b20caf4c57d7e41e5a5ea4aff460aef2ab upstream.

This is a static checker fix.  We write some binary settings to the
sysfs file.  One of the settings is the "->startup_profile".  There
isn't any checking to make sure it fits into the
pyra->profile_settings[] array in the profile_activated() function.

I added a check to pyra_sysfs_write_settings() in both places because
I wasn't positive that the other callers were correct.

HID: i2c-hid: prevent buffer overflow in early IRQ

2015-01-16T14:59:31+00:00

commit d1c7e29e8d276c669e8790bb8be9f505ddc48888 upstream.

Before ->start() is called, bufsize size is set to HID_MIN_BUFFER_SIZE,
64 bytes. While processing the IRQ, we were asking to receive up to
wMaxInputLength bytes, which can be bigger than 64 bytes.

Later, when ->start is run, a proper bufsize will be calculated.

Given wMaxInputLength is said to be unreliable in other part of the
code, set to receive only what we can even if it results in truncated
reports.

HID: i2c-hid: fix race condition reading reports

2015-01-16T14:59:31+00:00

commit 6296f4a8eb86f9abcc370fb7a1a116b8441c17fd upstream.

Current driver uses a common buffer for reading reports either
synchronously in i2c_hid_get_raw_report() and asynchronously in
the interrupt handler.
There is race condition if an interrupt arrives immediately after
the report is received in i2c_hid_get_raw_report(); the common
buffer is modified by the interrupt handler with the new report
and then i2c_hid_get_raw_report() proceed using wrong data.

Fix it by using a separate buffers for synchronous reports.

HID: usbhid: enable always-poll quirk for Elan Touchscreen

2014-11-14T17:00:06+00:00

commit bfe3c873e978d78b542a5852575dd74f4d1a5838 upstream.

Enable the always-poll quirk for Elan Touchscreens found on some recent
Samsung laptops.

Without this quirk the device keeps disconnecting from the bus (and is
re-enumerated) unless opened (and kept open, should an input event
occur).

Note that while the device can be run-time suspended, the autosuspend
timeout must be high enough to allow the device to be polled at least
once before being suspended. Specifically, using autosuspend_delay_ms=0
will still cause the device to disconnect on input events.

HID: usbhid: add always-poll quirk

2014-11-14T17:00:06+00:00

commit 0b750b3baa2d64f1b77aecc10f20deeb28efe60d upstream.

Add quirk to make sure that a device is always polled for input events
even if it hasn't been opened.

This is needed for devices that disconnects from the bus unless the
interrupt endpoint has been polled at least once or when not responding
to an input event (e.g. after having shut down X).

HID: logitech-dj: prevent false errors to be shown

2014-10-05T21:52:12+00:00

commit 5abfe85c1d4694d5d4bbd13ecc166262b937adf0 upstream.

Commit "HID: logitech: perform bounds checking on device_id early
enough" unfortunately leaks some errors to dmesg which are not real
ones:
- if the report is not a DJ one, then there is not point in checking
  the device_id
- the receiver (index 0) can also receive some notifications which
  can be safely ignored given the current implementation

Move out the test regarding the report_id and also discards
printing errors when the receiver got notified.
