Hi David,
Today's linux-next merge of the net tree got a conflict in
drivers/net/wireless/iwlwifi/iwl-tx.c between commit
3995bd9332a51b626237d6671cfeb7235e6c1305 ("iwlwifi: fix TX queue race")
from the wireless-current tree and commit
45af81956e990440fe78d6d41f847664cb620609 ("iwlwifi: make software queue
assignment more efficient") from the net tree.
Just overlapping context. I fixed it up (see below) and can carry the
fix as necessary.
