Subject: mac80211: pass channel to ieee80211_send_probe_req
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fe94fe05e9fb7c1bea482d1b0fd09029a711cce2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mac80211: pass channel to ieee80211_send_probe_req

In multi-channel scenarios, the channel that we will
transmit a probe request on isn't always the current
channel (which will be NULL anyway) but will instead
be the channel that the AP is on. Pass the channel
to the ieee80211_send_probe_req() function so it can
be used in the different scenarios. The scan code
continues to pass the current channel, of course.
