[PATCH 5.13 133/300] drm: rcar-du: Dont put reference to drm_device in rcar_du_remove()

[Greg Kroah-Hartman]

From: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>

[ Upstream commit c29b6b0b126e9ee69a5d6339475e831a149295bd ]

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..

Fixes: ea6aae151887 ("drm: rcar-du: Embed drm_device in rcar_du_device")
