Subject: mac80211: Allow AUTH_DATA to be used for FILS
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6ec63612c3c8da200d040dd4846d646a747722df;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mac80211: Allow AUTH_DATA to be used for FILS

The special SAE case should be limited only for SAE since the more
generic AUTH_DATA can now be used with other authentication algorithms
as well.
