This is a note to let you know that I have just added a patch titled regmap: Fix regmap_bulk_read in BE mode to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt15. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From d8dfc58177716f31c927ad05f472e02ade8eadc3 Mon Sep 17 00:00:00 2001 From: Arun Chandran <achandran@mvista.com> Date: Mon, 15 Jun 2015 15:59:02 +0530 Subject: regmap: Fix regmap_bulk_read in BE mode commit 15b8d2c41fe5839582029f65c5f7004db451cc2b upstream. In big endian mode regmap_bulk_read gives incorrect data for byte reads. This is because memcpy of a single byte from an address after full word read gives different results when endianness differs. ie. we get little-end in LE and big-end in BE.
