Subject: mtd: nand: atmel: Fix get_sectorsize() function
X-Git-Tag: v4.16~12^2~1
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=2b1b1b4ac716fd929a2d221bd4ade62263bed915;p=uclinux-h8%2Flinux.git

mtd: nand: atmel: Fix get_sectorsize() function

get_sectorsize() was not using the appropriate macro to extract the
ECC sector size from the config cache, which led to buggy ECC when
using 1024 byte sectors.
