X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=ab3c9ccb615032d18b2395ca2d68523fc1565dc3;p=openwrt%2Fstaging%2Fsvanheule.git

mediatek: filogic: fix sysupgrade on MMC on the BPi-R3

A previous attempt to simplify things went wrong and now sysupgrade
is broken on this device. Fix that.

Fixes: de94587e70 ("mediatek: filogic: don't rely on image preset in flash or sysupgrade")
