Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts: drivers/net/caif/caif_hsi.c drivers/net/usb/qmi_wwan.c The qmi_wwan merge was trivial. The caif_hsi.c, on the other hand, was not. It's a conflict between 1c385f1fdf6f9c66d982802cd74349c040980b50 ("caif-hsi: Replace platform device with ops structure.") in the net-next tree and commit 39abbaef19cd0a30be93794aa4773c779c3eb1f3 ("caif-hsi: Postpone init of HIS until open()") in the net tree. I did my best with that one and will ask Sjur to check it out. Signed-off-by: David S. Miller <davem@davemloft.net>
