Subject: linux-next: manual merge of the omap_dss2 tree with the arm-soc
tree
Hi Tomi,
Today's linux-next merge of the omap_dss2 tree got a conflict in
arch/arm/mach-omap2/board-ldp.c between commit 8f5b5a41ebc7 ("ARM: OMAP:
Introduce SoC specific early_init") from the arm-soc tree and commit
14dd72d8542f ("OMAP: LDP: Port the display driver to new DSS2") from the
omap_dss2 tree.
Just context changes. I fixed it up (I think - see below) and can carry
the fix as necessary.

Cheers,
