From: Mark Brown <[email protected]> This patch has been added to the 3.12 stable tree. If you have any objections, please let us 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.
