Subject: mtd: nand: vf610: return error code of nand_scan_ident/tail() on error
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e9d354b4b26aa8fe18b3a6858f2161a43a040e1f;p=linux-beck.git

mtd: nand: vf610: 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 -ENXIO.
