Message-ID: <442844a1add7446a8d5d2d91229fc0f043363381.1458760750.git.mchehab@osg.samsung.com> (raw)

Only MEDIA_IOC_ENUM_LINKS32 require an special logic when
userspace is 32 bits and Kernel is 64 bits.

For the rest, media_device_ioctl() will do the right thing,
and will return -ENOIOCTLCMD if the ioctl is unknown.
