Subject: linux-next: manual merge of the m68knommu tree with Linus' tree
Hi Greg,
Today's linux-next merge of the m68knommu tree got a conflict in
arch/m68k/platform/coldfire/clk.c between commit 19a1d332cc8c
("m68knommu: define a local devm_clk_get() function") from Linus' tree
and commit a0412a2ddaa3 ("m68knommu: Add support for the Coldfire
m5441x") from the m68knommu tree.
I fixed it up (I think - see below) and can carry the fix as necessary.

Cheers,
Stephen Rothwell sfr@...b.auug.org.au
