[PATCH] drm: rcar-du: Use drm_dev_put

[Vaishali Thakkar]

As specified in drm_drv.c, drm_dev_unref is a compatibility alias
for drm_dev_put and shouldn't be used in new code. So, use
drm_dev_put instead.

Hi Vaishali,

Thank you for the patch.

This looks good to me. However, how about taking it one step further and mass-
patching all drivers to use drm_dev_put() ? We could then remove 
drm_dev_unref() completely.

Sure thing! Do you want me to fold this patch in that patchset or will you be
fine with applying this separately?

I don't think we should split the change in one patch per driver, so if you 
send a single patch (to be applied through drm-misc) I think it would make 
sense to fold this change in.
