[PATCH] nouveau reclocking on nv40 not working since 77145f1cbdf8d28b46ff8070ca749bad821e0774

[Pali Rohár]

Hello,

in commit 77145f1cbdf8d28b46ff8070ca749bad821e0774 was introduced
error which cause that on my Nvidia 6600GT card reclocking not working
anymore. There is missing assigment of return value from pll_calc to ret.

After this patch reclocking on my card working fine again. Above broken
commit was introduced in kernel 3.7, so consider backporting this patch
to older kernels too.
