I honestly don't think this deserves a patch. Next time you work on
this driver, add the cleanups to it. But on its own, it's only churn.

Thanks,

While you are technically right, it's only churn I think we need this
for code consistency and cleanup.

Even if we fix this when we work on the driver we still need
to make the cleanup in a separate patch.

My 2 cents,
Daniel.

Get real. We really don't. Two blank lines do not lead to a
misinterpretation of the code, do not get in the way of normal
maintenance, do not lead to *any* practical issue.

What's next? Cc stable?

Neither. As well as removing blank lines, you could also remove the
dead code in this driver. That would be a good cleanup. You could
also have a look at what feels like a potential deadlock in the
mask/unmask callbacks. That'd be a good thing to do too.

Certainly more useful than just dropping two blank lines.
