Subject: mtd: nand: mediatek: return error code of nand_scan_ident/tail() on error
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f0dbe4aa35e73e4282d9446abb8900ab0636d483;p=linux-beck.git

mtd: nand: mediatek: return error code of nand_scan_ident/tail() on error

The nand_scan_ident/tail() returns an appropriate error value when
it fails.  Use it instead of the fixed error code -ENODEV.
