[PATCH 5.4 008/111] mtd: spinand: Propagate ECC information to the MTD structure

[Greg Kroah-Hartman]

From: Miquel Raynal <miquel.raynal@xxxxxxxxxxx>

[ Upstream commit 3507273d5a4d3c2e46f9d3f9ed9449805f5dff07 ]

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.

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