Are we sure this is safe? The remove handler appears to be written to disable pm_runtime at the start presumably to stop the resume/suspend handler running during the remove callback. Whereas after this change the pm_runtime isn't disabled until after the remove callback has run. Does this open a window were we could get an erroneous pm_runtime suspend after the pm_runtime_put_noidle?
Thanks, Charles
