[ Upstream commit 2e4b88f73966adead360e47621df0183586fac32 ]
In remove, the clock is disabled before canceling the delayed work. This means that the delayed work may be touching unclocked hardware.
Fix by disabling the clock after the delayed work is fully canceled. This is consistent with the probe error path order.
