Hi all,

Today's linux-next merge of the usb tree got a conflict in:

  drivers/usb/gadget/udc/core.c

between commit:

  f22e9b67f19c ("Revert "usb: gadget: udc: core: Invoke usb_gadget_connect only when started"")

from the usb.current tree and commit:

  d34f9bafa78d ("usb: gadget: udc: Handle gadget_connect failure during bind operation")

from the usb tree.

I fixed it up (I think - 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.
