This is a note to let you know that I have just added a patch titled regmap: Don't attempt block writes when syncing cache on single_rw devices to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.8. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 1a586d0c34837b1ad5195d06c89993323926f2aa Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@linaro.org> Date: Wed, 27 Aug 2014 13:09:12 +0100 Subject: regmap: Don't attempt block writes when syncing cache on single_rw devices 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.
