Subject[PATCH 3/3] staging: panel: remove initialization check
Date
no need to monitor init_in_progress now as keypad_send_key() can only
be called after the timer is initialized. and timer is initialized
from keypad_init() which is in the attach section and can only execute
after the module has initialized.
