-Subject: [PATCH] fix-jack-debounce.patch
-
-Headphone jack detection is bouncy, it can trigger multiple interrupts
-on insertion or removal.  This patch adds a workqueue that waits out the
-interrupt spew in 100ms units, and if it sees no more interrupts for 100ms
-only then samples and reports the jack state.  I was unable to get a bounce
-after 20 or so tries after this.
