drm/sun4i: crtc: Propagate layer initialization error

Browse source

sun4i_crtc_init() returns plain NULL when layer initialization fails,
while all its other error paths return an error pointer. The only
caller, sun4i_tcon_bind(), checks the result with IS_ERR() and happily
continues with tcon->crtc set to NULL. sun4i_rgb_init() and
sun4i_lvds_init() then dereference it in drm_crtc_mask(), which
oopses.

Return the error pointer instead.
