6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
[ Upstream commit ff3670877e7c73d06c2a835d9abb62efcae0145c ]
The struct imx_lcdc driver data is allocated using devm_drm_dev_alloc()
so it must not be explicitly kfree()d.
Also drm_kms_helper_poll_fini() should not be called as there is no
matching drm_kms_helper_poll_init(). So drop the release function
completely.
Fixes: c87e859cdeb5 ("drm/imx/lcdc: Implement DRM driver for imx25")
