Hi Mark,

After looking into this more carefully, I've decided to drop this patch.

My original intention was to keep the mutex_unlock()/mutex_lock() pair
in wcd_cancel_hs_detect_plug().
However, this function is also called from other places, and I'm not
confident that keeping
the manual mutex operations there would work correctly if those
callers use guard() or scoped_guard().

Best regards,
Phuc
