gpio: mpsse: ensure worker is torn down
[ Upstream commit 179ef1127d7a4f09f0e741fa9f30b8a8e7886271 ]
When an IRQ worker is running, unplugging the device would cause a
crash. The sealevel hardware this driver was written for was not
hotpluggable, so I never realized it.
This change uses a spinlock to protect a list of workers, which
it tears down on disconnect.
