Subject: linux-next: manual merge of the extcon tree with the usb tree

Hi all,

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

  drivers/usb/dwc3/drd.c

between commit:

  0f0101719138 ("usb: dwc3: Don't switch OTG -> peripheral if extcon is present")

from the usb tree and commit:

  88490c7f43c4 ("extcon: Fix extcon_get_extcon_dev() error handling")

from the extcon tree.

I fixed it up (the former moved the code modified by the latter, so I
used the former version of this files and added the following merge fix
patch) 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.
