For the m68k issues this is not a candidate for stable. The breakage
that this fixes did not occur until the 3.6 merge window.

The fact that it fixes some breakage on some m68k platforms is more
of a side effect, and the original patch author would not have known
about this. The underlying problem was with the local m68k/coldfire
implementation of devm_clk_get, but this patch makes that code go
away completely.
