Subject: ubi: reset mtd_devs when ubi part fail
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=40da2a2a08f12015d06d78a334e4d977963fee34;p=project%2Fbcm63xx%2Fu-boot.git

ubi: reset mtd_devs when ubi part fail

if "ubi part" fails, reset also mtd_devs to 0, as
further "ubi part" would use wrong mtd_devs.
