Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mach-imx/mach-imx6q.c between commit 1237f0f6ecf6 ("ARM: 7198/1:
arm/imx6: add restart support for imx6q") from the arm tree and commit
477fce49aef4 ("arm/imx6q-sabrelite: add enet phy ksz9021rn fixup") from
the arm-soc tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.

Cheers,
