This flash-chip is used on the Asus TUF-AX4200 and TUF-AX6000 routers. As the filogic target only uses kernel 5.15, skip the 5.10 backport. Signed-off-by: David Bauer <mail@david-bauer.net>

Subject: [PATCH] mtd: spinand: winbond: fix flash identification
|
|
|
|
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
|
|
identification. 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.
