Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mach-spear13xx/spear13xx.c between commit b47394911c26 ("ARM:
SPEAr13xx: Pass DW DMAC platform data from DT") from the slave-dma tree
and commit 3e270ba6e915 ("ARM: SPEAr13xx: Remove fields not required for
ssp controller") from the arm-soc tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
