Subject: [media] return -ENOTTY for unsupported ioctl's at legacy drivers
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7a286cc1889f14c5c8dbf866718edde100527d8c;p=openwrt%2Fstaging%2Fblogic.git

[media] return -ENOTTY for unsupported ioctl's at legacy drivers

Those drivers are not relying at the V4L2 core to handle the ioctl's.
So, we need to manually patch them every time a change goes to the
core.
