VDDPU is needed for using the GPU, so the kernel should turn on the
VDDPU regulator.

Looks like you are getting a kernel bug.

It might be but shouldn't we delay this patch for now?

Now or later it does not change. The correct behavior is done with the patch, and the kernel must turn power on. If it does not, the patch is needed for the kernel, not here.

I've been debugging to make 3.10 to work with this patch, but without success...

I think this patch should be reverted and be added back to 2014.04 release so we have more time to debug this.
