When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  Fix this up by properly
calling dput().

Despite a zillion cc: items, I forgot to cc: stable on this.  Can the
maintainer add that here, or do you all want me to resend it with that
item added?

thanks,

Hi Greg,

Reviewed-by: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx>

Is 'Cc: stable@xxxxxxxxxxxxxxx' enough here? I can make this change before I
merge it into amd-staging-drm-next.

Yes, please add the cc: stable@ line to the body of the patch, sorry I
forgot that.


Change applied to amd-staging-drm-next, with the Cc to the stable branch.

Thanks
Siqueira

thanks,

greg k-h
