| Subject: regmap: Fix regmap_bulk_read in BE mode |
| |
| From: Arun Chandran <achandran@mvista.com> |
| |
| 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. |
