Subject: v4l2-ioctl: properly return -EINVAL when parameters are wrong
X-Git-Tag: v3.2-rc1~112^2~338

v4l2-ioctl: properly return -EINVAL when parameters are wrong

Whan an ioctl is implemented, but the parameters are invalid,
the error code should be -EINVAL. However, if the ioctl is
not defined, it should return -ENOTTY instead.
