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

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

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