Subject: media: rc-main: clean-up two warnings
Author: Mauro Carvalho Chehab <mchehab+sams...@kernel.org>
Date: Thu May 23 05:27:30 2019 -0400
While correct, the code is too complex for smatch to undersdand
that protocol will always be initialized:
drivers/media/rc/rc-main.c:1531 store_wakeup_protocols() error:
uninitialized symbol 'protocol'.
drivers/media/rc/rc-main.c:1541 store_wakeup_protocols() error:
uninitialized symbol 'protocol'.
So, change it a little bit in order to avoid such warning.
