[PATCH] drm/cma-helper: Return ENOENT for "no such gem obj"

[Daniel Vetter <daniel.vetter@ffwll.ch>]

All the error codes we (ab)use are strictly not the right ones (since
they're all for the vfs, and the only thing we're allowed to do from
an ioctl is EINVAL). But ENOENT is the common error code for failed to
look up an object throughout drm, so let's use it in the cma helpers,
too.
