X-Git-Tag: v19.07.0-rc1~16117
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1183af0c48998a73595b92381ce0ba39aec19951;p=openwrt%2Fstaging%2Fhauke.git

lantiq: vr9-vdsl-fw: properly write firmware to flash

Using a redirect to a non-empty mtd partition will not erase the
blocks prior to writing to them resulting in broken dsl_fw.
Fix this by piping to mtd write - /dev/mtdX instead.
