4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Haneen Mohammed <hamohammed...@gmail.com>
commit 7f6df440b8623c441c42d070bf592e2d2c1fa9bb upstream.
This patch matches the sysfs name used in the unlinking with the
linking function. Otherwise, remove_compat_control_link() fails to remove
sysfs created by create_compat_control_link() in drm_dev_register().
Fixes: 6449b088dd51 ("drm: Add fake controlD* symlinks for backwards
compat")
