Subject: [media] usbvision: remove g/s_audio and for radio remove enum/g/s_input
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=601ecab34bab60896aa135ebde0d2b629d491821;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[media] usbvision: remove g/s_audio and for radio remove enum/g/s_input

The g/s_audio ioctls didn't do anything, so remove them all for both
video and radio nodes and remove V4L2_CAP_AUDIO.

The enum/g/s_input ioctls are invalid for radio nodes, so remove them
from the radio ioctl_ops.
