Hi all,
Today's linux-next merge of the net-next tree got a conflict in
drivers/net/wireless/mwifiex/pcie.c between commit bb8e6a1ee881
("mwifiex: add NULL check for PCIe Rx skb") from the tree and commit
dbccc92b5d54 ("mwifiex: balance dma map/unmap sizes") from the net-next
tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
