Thanks for fixing this. Looks like this should be queued by the
drivers/power/avs maintainers and there should not be merge
conflicts with other omap changes queued.

Maybe do $ scripts/get_maintainer.pl -f drivers/power/avs
and resend both patches to the maintainers?

One comment below on the clocks though..

Here you should not pass clocks around. The driver should be able to
clk_get(dev, "fck") as long as you have the proper CLK() aliases set
in the arch/arm/mach-omap2/clock*_data.c files.
