Could you confirm this should *not* be added to 3.5 kernels?

This patch fixes issue introduced by commit e9da6e9905e639b0f842a244bc770b48ad0523e9, which has been merged to v3.6-rc1. All v3.5.x and earlier are not affected by this bug. I should have added such information to commit message to avoid confusion.
