Subject: V4L/DVB (5152): Implements VIDIOC_[S|G]_INPUT on radio-aztech/radio-maxiradio
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a0c05ab9762560cf12733181d19b6529bb7231d2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

V4L/DVB (5152): Implements VIDIOC_[S|G]_INPUT on radio-aztech/radio-maxiradio

fmtools use VIDIOCSTUNER, with, in turn, calls VIDIOC_S_INPUT on v4l1-compat.
So, those ioctls are required for V4L1  to work properly.
