[PATCH] dvb: Twinhan DST: frontend fixes
o Make the inversion setting specific, ie, only for the 200103A DVB-S This should not be flagged on other cards. o Make the frequency setting card specific o Make the bandwidth setting generic such that it supports more DVB-T cards o Set QAM size for DVB-C cards that do not autodetect QAM size o Fix a bug that caused the polarization not to be set. Set polarization for cards that do not autodetect polarization o Fix a bogus frontend signal lock, that caused a tuning delay as well. o Make the Symbolrate setting card specific Signed-off-by: Manu Abraham <manu@kromtek.com> Signed-off-by: Johannes Stezenbach <js@linuxtv.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
