When testing what happens when randomly configuring and unconfiguring
a CEC adapter, and simultaneously setting an invalidating the physical
address, and starting and stopping monitoring and pin monitoring using
two cec-gpio instances, a whole bunch of race conditions were found.

This patch series addresses them.

Hans Verkuil (7):
  cec-pin: disabling the adapter cannot call kthread_stop
  cec-pin: don't zero work_pin_num_events in adap_enable
  cec-adap.c: don't unconfigure if already unconfigured
  cec-adap.c: stop trying LAs on CEC_TX_STATUS_TIMEOUT
  cec-adap.c: fix is_configuring state
  cec-adap.c: reconfigure if the PA changes during configuration
  cec-adap: drop activate_cnt, use state info instead
