Subject: [PATCH 06/24] drm/xlnx: Use devm_drm_dev_alloc
Date: Fri,  4 Sep 2020 16:39:23 +0200
Message-ID: <20200904143941.110665-7-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20200904143941.110665-1-daniel.vetter@ffwll.ch>

Gets rid of drmm_add_final_kfree, which I want to unexport so that it
stops confusion people about this transitional state of rolling drm
managed memory out.

This also fixes the missing drm_dev_put in the error path of the probe
code.
