A bulk read can be implemented either through regmap_raw_read, or by reading each register individually using regmap_read. Both regmap_read and regmap_bulk_read should return values in native endian. In the individual case the current implementation calls format_val to put the data into the output array, which can cause endian issues. The regmap_read will have already converted the data into native endian, if the hosts endian differs from the device then format_val will switch the endian back again. Rather than using format_val simply use the code that is called if there is no format_val function. This code supports all cases except 24-bit but there don't appear to be any users of regmap_bulk_read for 24-bit. Additionally, it would have to be a big endian host for the old code to actually function correctly anyway.
