Hi Felipe,
Today's linux-next merge of the usb-gadget tree got a conflict in
drivers/usb/musb/musb_cppi41.c between commit c58d80f523ff ("usb: musb:
Ensure that cppi41 timer gets armed on premature DMA TX irq") from the
usb.current tree and commit 50aea6fca771 ("usb: musb: cppi41: fire
hrtimer according to programmed channel length") from the usb-gadget
tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
