Hi all,

After merging the mac80211-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/wireless/ath/ath10k/wmi.c: In function 'ath10k_wmi_event_mgmt_rx':
drivers/net/wireless/ath/ath10k/wmi.c:2626:12: error: too few arguments to function 'cfg80211_get_ies_channel_number'
 2626 |   ies_ch = cfg80211_get_ies_channel_number(mgmt->u.beacon.variable,
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  7f599aeccbd2 ("cfg80211: Use the HE operation IE to determine a 6GHz BSS channel")

interacting with commit

  3bf2537ec2e3 ("ath10k: drop beacon and probe response which leak from other channel")

from the net-next tree.

I have applied the following merge fix patch for today (which, on
reflection, may not be correct, but builds).
