HID: microsoft: Add ID for NE7K wireless keyboard

2015-02-23T14:28:40+00:00

Microsoft Natural Wireless Ergonomic Keyboard 7000 has special My
Favorites 1..5 keys which are handled through a vendor-defined usage
page (0xff05).

Apply MS_ERGONOMY quirks handling to USB PID 0x071d (Microsoft Microsoft
2.4GHz Transceiver V1.0) so that the My Favorites 1..5 keys are reported
as KEY_F14..18 events.

HID: i2c-hid: Limit reads to wMaxInputLength bytes for input events

2015-02-23T14:10:04+00:00

d1c7e29e8d27 (HID: i2c-hid: prevent buffer overflow in early IRQ)
changed hid_get_input() to read ihid->bufsize bytes, which can be
more than wMaxInputLength. This is the case with the Dell XPS 13
9343, and it is causing events to be missed. In some cases the
missed events are releases, which can cause the cursor to jump or
freeze, among other problems. Limit the number of bytes read to
min(wMaxInputLength, ihid->bufsize) to prevent such problems.

HID: sony: Fix a WARNING shown when rmmod-ing the driver

2015-02-18T20:18:22+00:00

ida_destroy() must be called _after_ all the devices have been
unregistered; otherwise, when calling "rmmod hid_sony" with devices
still plugged in, the following warning would show up because of calls
to ida_simple_remove() on a destroyed ID allocator:

HID: i2c-hid: The interrupt should be level sensitive

2015-02-17T12:23:13+00:00

The Microsoft HID over I2C specification says two things regarding the
interrupt:

 1) The interrupt should be level sensitive
 2) The device keeps the interrupt asserted as long as it has more reports
    available.

We've seen that at least some Atmel and N-Trig panels keep the line low as
long as they have something to send. The current version of the driver only
detects the first edge but then fails to read rest of the reports (as the
line is still asserted).

Make the driver follow the specification and configure the HID interrupt to
be level sensitive.

The Windows HID over I2C driver also seems to do the same.
