[PATCH v2 14/23] mtd: spi-nor: winbond: W25Q128JV-Q/N: Fill locking information

[Miquel Raynal]

The SFDP table does not advertize the CMP locking capabilities of the
device, flag it.

The CMP capability was historically not supported by non-SFDP chips, so
a Winbond wide late hook already makes sure the bit remains disabled for
them, for backward compatiblity reasons.
