Subject: media: dvb_frontend: be sure to init dvb_frontend_handle_ioctl() return code
Author: Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxxxxx>
Date: Wed Nov 1 17:05:39 2017 -0400
As smatch warned:
drivers/media/dvb-core/dvb_frontend.c:2468 dvb_frontend_handle_ioctl() error: uninitialized symbol 'err'.
The ioctl handler actually got a regression here: before changeset
d73dcf0cdb95 ("media: dvb_frontend: cleanup ioctl handling logic"),
the code used to return -EOPNOTSUPP if an ioctl handler was not
implemented on a driver. After the change, it may return a random
value.
Fixes: d73dcf0cdb95 ("media: dvb_frontend: cleanup ioctl handling logic")
