Subject: mac80211: do not call ieee80211_configure_filter if no interfaces are up
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=35f5149ead73e8e635b417b6c3aece43ffdfe5bc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mac80211: do not call ieee80211_configure_filter if no interfaces are up

Drivers are not expected to handle it before drv_start has been called. It
will be called again after an interface has been brought up.
