Hi Sheng-Liang,

Hmm, if ATKBD_CMD_RESET_DIS causes keyboard not working should we
simply not call it on LG devices?

The idea for using ATKBD_CMD_RESET_DIS was for keyboard to stop
generating scan codes so they do not interfere with detection/resume and
issuing ATKBD_CMD_RESET_DEF right after ATKBD_CMD_RESET_DIS keeps
keyboard in exactly the same state as it was before (i.e. generating
scancodes).

Thanks.
