We used this patch for a long time. So, I guess it is stable.

You misunderstood. Should this patch be marked for backporting to older
kernels because it fixes a critical issue on devices otherwise working
in that kernel? See Documentation/stable_kernel_rules.txt

Sorry. As I understand from the stable_kernel_rules.txt this patch _IS_ 
_NOT_ for "-stable"
