Re: [PATCH 1/6] drm: sun4i: do cleanup if RGB output init fails

sun4i_rgb_init() can fail, which results in TCON failing to bind. In this case we need to do cleanup, specificly unregistering the dotclock, which is regmap based, and the regmap is registered as part of the sun4i_tcon_bind().

Failing to do so results in a NULL pointer reference when the CCF tries to turn off unused clocks.
