Please be more specific with commit messages -- is there an observed

I kind of expected this change was pretty obvious.

 is there an observed symptom that this fixes?

None. I noticed this misuse, so I fixed it.

 Does the patch need to go to stable@, too?

No, this driver is in -next currently.

 Thanks,
 
 - Chris.

Best regards,
Marek Vasut
