I assume you mean "nvidia-open"? Unless I'm missing something, it's not possible to patch the proprietary drivers.

You are right, I did not see that this patch is only for nvidia open driver, Maybe I should close this task and reopen a task for nvidia-open and nvidia-open-dkms.

Check nvidia-open in testing. Does that work for you?
