6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
[ Upstream commit 5f1fee9644759d07f3d3a468389c7c18027083d7 ]
If non-BSS and remain-on-channel (ROC) blocking were to occur
simultaneously, they'd step on each other's toes, unblocking
when not yet supported. Disentangle these bits, and ROC doesn't
need to use the non_bss_link() function then.
Fixes: a1efeb823084 ("wifi: iwlwifi: mvm: Block EMLSR when a p2p/softAP vif is active")
