Subject: mtd: Use get_mtd_device_nm() to find named device in get_sb_mtd()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=677c2aec8cdd5ae33b5fab266941cf6c6dc4d59f;p=openwrt%2Fstaging%2Fblogic.git

mtd: Use get_mtd_device_nm() to find named device in get_sb_mtd()

This removes the need to know the number of MTD devices.
