Subject: linux-next: manual merge of the pm tree with the imx-mxs tree

Hi Rafael,

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

  arch/arm/mach-imx/gpc.c

between commits:

  eef0b282bb58 ("ARM: imx: gpc: Initialize all power domains")
  f9d1f7a7ad91 ("ARM: imx: gpc: Fix the imx_gpc_genpd_init() error path")

from the imx-mxs tree and commit:

  59d65b73a23c ("PM / Domains: Make genpd state allocation dynamic")

from the pm 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.

Cheers,
Stephen Rothwell
