Subject: V4L/DVB: lgdt3305: enable FE_HAS_SIGNAL hack for the lgdt3304 in QAM mode
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a5ba334cda924eb0ae4754321ad7fc292c5a5288;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

V4L/DVB: lgdt3305: enable FE_HAS_SIGNAL hack for the lgdt3304 in QAM mode

The signal bit is unreliable on the DT3304 in QAM mode, so
set FE_HAS_SIGNAL based on 'cr_lock'
