Subject: [PATCH 33/51] drm/mcde: More devm_drm_dev_init
Date: Thu, 27 Feb 2020 19:15:04 +0100	[thread overview]
Message-ID: <20200227181522.2711142-34-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200227181522.2711142-1-daniel.vetter@ffwll.ch>

Auto-unwind ftw, now possible with the fixed drm_device related
management.

Aside, clk/regulator seem to be missing devm versions for a bunch of
functions, preventing a pile of these simpler drivers from outright
losing their ->remove hook.
