[PATCH v15 1/8] mtd: spi-nor: s/addr_width/addr_nbytes

tkuw584924
2022-05-09T22:10:56Z

From: Tudor Ambarus <tudor.ambarus@microchip.com>

Address width was an unfortunate name, as it means the number of IO lines
used for the address, whereas in the code it is used as the number of
address bytes. s/addr_width/addr_nbytes throughout the entire SPI NOR
framework.
