Subject: [media] dib0090: Do the right check for state->rf_ramp
Author:  Mauro Carvalho Chehab <[email protected]>
Date:    Sat Feb 27 07:51:09 2016 -0300

Smatch with -pkernel --no-data keeps complaining about rf_ramp:
        drivers/media/dvb-frontends/dib0090.c:1119 dib0090_pwm_gain_reset() 
error: we previously assumed 'state->rf_ramp' could be null (see line 1086)
