mtd: rawnand: onfi: Fix endianness when reading NV-DDR values
Without the use of le16_to_cpu(), these accesses would have been wrong
on a big-endian machine.
Reported-by: kernel test robot <lkp@intel.com>
Fixes: 45606518f961 ("mtd: rawnand: Add onfi_fill_nvddr_interface_config() helper")
Fixes: 9310668fb60a ("mtd: rawnand: Retrieve NV-DDR timing modes from the ONFI parameter page")
