Subject: [PATCH v3 37/40] mtd: spinand: Propagate ECC information to the MTD structure

From: Miquel Raynal <[email-masked]>
Date: Thu, 19 Sep 2019 21:31:37 +0200

This is done by default in the raw NAND core (nand_base.c) but was
missing in the SPI-NAND core. Without these two lines the ecc_strength
and ecc_step_size values are not exported to the user through sysfs.

This fix depends on recent changes and should not be backported as-is.

Fixes: 7529df465248 ("mtd: nand: Add core infrastructure to support SPI NANDs")
