[PATCH 3.0-rc1 v2] Input: omap-keypad: add missing input_sync()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Otherwise the updated evdev driver (commit cdda911c34006f1089f3c87b1a1f, 
"Input: evdev - only signal polls on full packets") no longer works on 
top of omap-keypad.

Tested on Amstrad Delta.

v1 -> v2 change, suggested by Henrik Rydberg (thanks!):
- no need for a special variable tracing if input_sync is required - 
  the input core already does the same thing.
