Subject: keyboard.c: stop flooding dmesg with useless warnings
From: Parag Warudkar <parag.warudkar@xxxxxxxxx>
I use Apple keyboard and mouse which seem to generate events with
keycode==0.
keyboard.c floods dmesg endlessly with below messages. This happens at a
very fast rate and never stops, leaving the dmesg unusable.
[46591.960000] keyboard.c: can't emulate rawmode for keycode 0
[46591.996000] keyboard.c: can't emulate rawmode for keycode 0

[46592.104000] keyboard.c: can't emulate rawmode for keycode 0
[46592.140000] keyboard.c: can't emulate rawmode for keycode 0

[46592.212000] keyboard.c: can't emulate rawmode for keycode 0
[46592.248000] keyboard.c: can't emulate rawmode for keycode 0
The patch below avoids printing the warning if keycode == KEY_RESERVED.
