ASoC: wcd9xxx: Check headset insertion for consistency
 * It's possible to get a noisy reading during polling when
   transitioning to PLUG_TYPE_HEADSET. Poll again to double
   check that it's really a headset.
 * This helps when music is at full volume and a headphone
   is inserted. Double-checking the reading vastly improves
   the case where a noisy reading causes a mic to be detected.

CHROMIUM: mm: Fix calculation of dirtyable memory

The system uses global_dirtyable_memory() to calculate
number of dirtyable pages/pages that can be allocated
to the page cache.  A bug causes an underflow thus making
the page count look like a big unsigned number.  This in turn
confuses the dirty writeback throttling to aggressively write
back pages as they become dirty (usually 1 page at a time).

Fix is to ensure there is no underflow while doing the math.
