Also this is not the right goto. We should be turning the clk off.

I don't really care for the naming scheme, and I know you renamed it for
me already once and I feel bad for not liking it more. It's still
really a come-from label name and doesn't say what the goto does...
Instead of post_clk_err, I wish it had names like "err_clk_off:".

And in this case what it does is print a duplicative error message and
return. :/ The goto post_drvdata_err: lines should just print their
own error messages if needed and return directly. If there is no
cleanup then there is no need for a goto.

Anyway, that's not related to this patch. Just resend it with
goto post_clk_err: in the v2.
