Hi all,

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

  drivers/extcon/extcon.c

between commit:

  1aaba11da9aa ("driver core: class: remove module * from class_create()")

from the driver-core tree and commit:

  6384c02f33a9 ("extcon: Remove redundant null checking for class")

from the extcon 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.

Thanks, the merge resolution looks good to me.
