Is the intention just to save a few lines in the kernel source, or are
there any additional upsides to doing this?

While it looks like an obvious cleanup, it also seems to me that there
is zero effect in terms of functionality, code size or enabling future
changes.

I'm all for adding your semantic patch to scripts/coccinelle so it gets
picked up by anyone writing new drivers or doing code cleanup on their
driver, but I'm unsure about the value of applying all your patches
for the existing drivers.
