From 15b8d2c41fe5839582029f65c5f7004db451cc2b Mon Sep 17 00:00:00 2001 From: Arun Chandran Date: Mon, 15 Jun 2015 15:59:02 +0530 Subject: [PATCH] regmap: Fix regmap_bulk_read in BE mode 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.
