| |
3.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@linaro.org>
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.
