[PATCH] : HP Jornada 680 Keyboard support
|
From: Kristoffer E. <kri...@gm...> - 2007-07-16 21:43:13

Greetings,
Paul could you just give this a check. Im working on scan_keyb and that should be ready tommorow.
This patch is based on what andriy made with my additions :
Keymap now uses KEY_X instead of 0x00..
Fixed for dead keys, so they all work.
Best wishes
Kristoffer
