drm/imx: tve: fix regulator_disable error path
Add missing regulator_disable() as devm_action to avoid dedicated unbind() callback and fix the missing error handling. Fixes: fcbc51e54d2a ("staging: drm/imx: Add support for Television Encoder (TVEv2)") Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
