From: Arun Chandran <achandran@xxxxxxxxxx> This patch has been added to the 3.18 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 15b8d2c41fe5839582029f65c5f7004db451cc2b ] 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.
