Subject: lib80211: ratelimit key index mismatch
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=996bf99c71944590e4f56504d5ec99ddd0d85e9c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

lib80211: ratelimit key index mismatch

This indicates a driver key selection issue, but even then there's
no point in printing it all the time, so ratelimit it. Also remove
the priv pointer from it -- people debugging will only have a single
device anyway and it's useless as anything but a cookie.
