Subject: [media] radio-timb: add device_caps support, remove input/audio ioctls
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d020f83947c68d9d6e8848fe81cc630ef603d177;p=openwrt%2Fstaging%2Fblogic.git

[media] radio-timb: add device_caps support, remove input/audio ioctls

The audio and input ioctls are not applicable for radio devices,
remove them.
Also set the device_caps field in v4l2_querycap.
