Hi Felipe,
Today's linux-next merge of the usb-gadget tree got a conflict in:
drivers/usb/gadget/udc/amd5536udc.c
between commit:
b5a6a4e5baef ("usb: gadget: amd5536udc: Replace PCI pool old API")
from the usb tree and commit:
7bf80fcd797f ("usb: gadget: udc: avoid use of freed pointer")
from the usb-gadget tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
