commit 42fb6b1d41eb5905d77c06cad2e87b70289bdb76 upstream.
CA0132 has the delayed HP jack detection code that is invoked from the unsol handler, but it does a few weird things: it contains the cancel of a work inside the work handler, and yet it misses the cancel-sync call at (runtime-)suspend. This patch addresses those issues.
