4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Arun Chandran <[email protected]> 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.
