[PATCH 2/4] drivers/media/dvb: Remove undead configs
From: Christian Dietrich
Date: Wed Jul 14 2010 - 09:21:28 EST
The following CONFIG_ options are set within the C File, so the blocks
will always be selected. For the matter of readability the ifdefs are
not nesseccary:
CONFIG_BAND_CBAND
CONFIG_BAND_UHF
CONFIG_BAND_VHF
CONFIG_DIB0090_USE_PWM_AGC
CONFIG_SYS_ISDBT
