This patch can go through the clock tree and won't cause any build
issues or run-time failure even on Tegra124 (except CPU hot plug stress
testing). Only some warning message would show up.

But I am going to send some other patches for platform suspend support
for Tegra124, it might meet the issue you mentioned here. We only can
test it in our local tree or wait for the next linux-next (20131028?)
for testing after everything merged. So it might be OK, I guess.
