[PATCH 1/2] mtd: spinand: winbond: fix winbond lashes identifications

From: mikhail . kshevetskiy
Date: Fri Oct 07 2022 - 06:41:23 EST


From: Mikhail Kshevetskiy <mikhail.kshevetskiy@xxxxxxxxx>

Winbond uses 3 bytes to identify flash: vendor_id, dev_id_0, dev_id_1,
but current driver uses only first 2 bytes of it for devices
idenfification. As result Winbond W25N02KV flash (id_bytes: EF, AA, 22)
is identified as W25N01GV (id_bytes: EF, AA, 21).

Fix this by adding missed identification bytes.
