Subject: [PATCH AUTOSEL 5.17 140/149] iwlwifi: mei: fix building iwlmei

From: Arnd Bergmann <arnd@...db.de>

[ Upstream commit 066291bec0c55315e568ead501bebdefcb8453d2 ]

Building iwlmei without CONFIG_CFG80211 causes a link-time warning:

ld.lld: error: undefined symbol: ieee80211_hdrlen
>>> referenced by net.c
>>>               net/wireless/intel/iwlwifi/mei/net.o:(iwl_mei_tx_copy_to_csme) in archive drivers/built-in.a

Add an explicit dependency to avoid this. In theory it should not
be needed here, but it also seems pointless to allow IWLMEI
for configurations without CFG80211.
