[PATCH v2 07/32] mtd: rawnand: fsl_ifc: convert driver to nand_scan()

From: Miquel Raynal
Date: Tue Jul 03 2018 - 18:07:44 EST


Two helpers have been added to the core to make ECC-related
configuration between the detection phase and the final NAND scan. Use
these hooks and convert the driver to just use nand_scan() instead of
both nand_scan_ident() and nand_scan_tail().
