   4 Subject: [PATCH] fix-pcf50633-mask-second-on-resume.patch
   5
   6 We leave SECOND unmasked on resume, it's like the
   7 situation at probe() time, but there it makes us
   8 turn SECOND off after coldplug action.  So we need
   9 to act like after that has happened, not exactly
  10 like what we do at probe / init time.
