Subject[PATCH v4 1/4] mtd: spi-nor: otp: fix access to security registers in 4 byte mode
Date
The security registers either take a 3 byte or a 4 byte address offset,
depending on the address mode of the flash. Thus just leave the
nor->addr_width as is.

Fixes: cad3193fe9d1 ("mtd: spi-nor: implement OTP support for Winbond and similar flashes")
