Subject: mac80211: fix change flags variable signedness
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b08cc24e0a24f8d67ba7d66dab43c40ed25a3f5c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mac80211: fix change flags variable signedness

This showed up as a sparse warning (with higher verbosity) and is
certainly correct - the change flags should be unsigned. It's not
that important since high flag numbers aren't used and bitwise
operations would still work.
