divider_u71 is unsigned, so this check is buggy:

If divider_u71 is 0 or 1 both checks are lying.
So, it does not produce a buggy answer, but it is confusing.

Hi Kulikov,

The first name is Vasiliy :)

Thanks for the patch. This problem has been fixed in another patch in
the linux-tegra tree, I'll post it for review and update the
linux-next tree soon.
