Okay. Would now only still like to know why the test in resume() means
trouble for you while it seems the same test in suspend() should've
triggered as well and not have stopped the device in the first place.
Know absolutely nothing about hibernation so added the listed maintainers to
Pavel, Rafael -- the attached fixes snd-cs4236 not coming back to life for
Ondrej after hibernation due to the PNP_DRIVER_RES_DO_NOT_CHANGE test
triggering in pnp_bus_resume() and keeping the card in a suspended state.
