Date: Fri, 3 Oct 2014 14:29:51 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Jarkko Nikula <jarkko.nikula@...ux.intel.com>, Mark Brown <broonie@...aro.org> Subject: [PATCH 3.16 205/357] regmap: Dont attempt block writes when syncing cache on single_rw devices 3.16-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mark Brown <broonie@...aro.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.
