[PATCH v2 0/4] drm: rcar-du: Improve device_link handling

[Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>]

Hello,

This small patch series came out of the review of [1].

I noticed that the DU driver enforces suspend/resume ordering with the
CMMs but not with the VSPs, which patch 1/4 fixes. This in turn made me
notice that the driver leaks the device_link instances to the CMM.
Patches 2/4 and 3/4 refactor CMM handling a bit, to prepare for 4/4 that
fixes the leak.

Changes compared to v1 are minor, see individual patches for details.
