Subject: [PATCH] drm: rcar-du: Don't put reference to drm_device in rcar_du_remove()
Git-commit: c29b6b0b126e9ee69a5d6339475e831a149295bd
Patch-mainline: v5.15-rc1
References: git-fixes stable-5.14.4
The reference to the drm_device that was acquired by
devm_drm_dev_alloc() is released automatically by the devres
infrastructure. It must not be released manually, as that causes a
reference underflow..
