From: Mark Brown <broonie@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 5c1ebe7f73f9166893c3459915db8a09d6d1d715 upstream.
If the device can't support block writes then don't attempt to use raw
syncing which will automatically generate block writes for adjacent
registers, use the existing _single() block syncing implementation.
