Subject: media: tc358743: clk_disable_unprepare(refclk) missed

Hello,

tc358743_probe_of() enables refclk and disables it on its error paths.
But there is no clk_disable_unprepare(refclk) in tc358743_remove()
and on error paths in tc358743_probe(). Is it a problem?

If we should fix it, is adding struct clk *refclk; to tc358743_state
the reasonable way to keep clk easily available?
