The commit log doesn't really explain much. What does this patch do
exactly?

In STA mode, if the host stays in ww regulatory doamin ("00"),
NL80211_DFS_UNSET would be set to driver. In such case, mt76 cannot
find out the proper dts node to limit power settings. We apply this
patch to have a proper power mapping for ww domain.

Ok. In the future, please always this kind of information to the commit
log. One vague phrase is not a proper commit log, more info about that
in the wiki below.
