With this change I get this warning:
drivers/media/dvb-core/dvb_frontend.c: In function ‘dvb_frontend_thread’:
drivers/media/dvb-core/dvb_frontend.c:695:6: warning: unused variable ‘ret’
[-Wunused-variable]
int ret;
^
So the 'ret' variable declaration should be under #ifdef
CONFIG_MEDIA_CONTROLLER_DVB
as well.

Hans
