Drop the else branch following an if that always returns, and move
the trailing comment onto the fall-through path. Cosmetic only, no
functional change; silences a checkpatch WARNING.

So what is the checkpatch warning? IMHO that change make the
readability worse.

It's the "else is not generally useful after a break or return"
check in checkpatch.pl.
Fair point. With the comments attached to both branches, the
symmetric if/else reads fine, and I agree this isn't worth
changing. Please drop this patch.
Sorry for the noise.
