From: Maxime Ripard maxime.ripard@free-electrons.com

commit 92411f6d7f1afcc95e54295d40e96a75385212ec upstream.

The commit 4c7f16d14a33 ("drm/sun4i: Fix TCON clock and regmap initialization sequence") moved a bunch of logic around, but forgot to update the gotos after the introduction of the err_free_dotclock label.

It means that if we fail later that the one introduced in that commit, we'll just to the old label which isn't free the clock we created. This will result in a breakage as soon as someone tries to do something with that clock, since its resources will have been long reclaimed.
