HID: wacom: check for wacom->shared before following the pointer

2015-03-17T19:59:55Z

486b908 (HID: wacom: do not send pen events before touch is up/forced out) introduces a kernel oops when plugging a tablet without touch. wacom->shared is null for these devices so this leads to a null pointer exception. Change the condition to make it clear that what we need is wacom->shared not NULL. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

HID: tivo: enable all buttons on the TiVo Slide Pro remote

2015-03-15T14:04:27Z

The linux kernel has supported the TiVo Slide remote control for some time, but does not recognize the USB ID of the newer Slide Pro. This patch adds the missing data structures so the newer remote will be recognized by the driver, thereby allowing the TiVo, LiveTV, and Thumbs Up/Down buttons to be mapped with a hwdb file.

HID: wacom: rely on actual touch down count to decide touch_down

2015-03-02T23:27:10Z

touch_down is a flag to indicate if there are touches on tablet or not. Since one set of touch events may be posted over more than one data packet/touch frame, and pen may come in proximity while touch events are partially sent, counting all touch events for the set reflects the actual status of touch_down.

HID: wacom: do not send pen events before touch is up/forced out

2015-03-02T23:27:09Z

If pen comes in proximity while touch is down, we force touch up before sending pen events. Otherwise, there can be unfinished touch events compete with pen events. This idea has been fully implemented for Tablet PCs. But other tablets that support both pen and touch are not fully considered. Signed-off-by: Ping Cheng Signed-off-by: Jiri Kosina

HID: microsoft: Add ID for NE7K wireless keyboard

2015-02-23T14:28:40Z

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

2015-02-23T14:10:04Z

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.
