For one thing it should not longer depend on INPUT_EVDEV=y. Now if DVB_AV7110=m and RC_CORE=y is not allowed which should be (this is the case in Fedora default kernel config for example). > depends on VIDEO_DEV # dependencies of VIDEO_SAA7146_VV > select DVB_VES1820 if MEDIA_SUBDRV_AUTOSELECT > select DVB_VES1X93 if MEDIA_SUBDRV_AUTOSELECT > -- > 2.7.4 > Thanks, Sean
