Subject: mtd: nand: hisi504: return error code of nand_scan_ident() on error
X-Git-Tag: v5.15~12218^2~4^2~22

mtd: nand: hisi504: return error code of nand_scan_ident() on error

The nand_scan_ident() returns an appropriate error value when it
fails.  Use it instead of the fixed error code -ENODEV.
(This driver is already doing so for nand_scan_tail().)
