- Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix
- Macronix flash chips seem to consist of only one status register.
- These chips will not work with the "16-bit Write Status (01h) Command".
- Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.
- Tested with MX25L6405D.
- Fixes: 39d1e3340c73 ("mtd: spi-nor: Fix clearing of QE bit on
- lock()/unlock()")
