3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Felix Fietkau <n...@openwrt.org>
commit c1227340ca65c2069222a956a68b6842d460c4f4 upstream.
With an uninitialized chainmask, the per-channel power will only contain
the power limits for a single chain instead of the combined tx power.
