[Qemu-devel] [PATCH] scripts/checkpatch.pl: Don't allow special cases of unspaced operators

[Peter Maydell <peter.maydell@linaro.org>]

The checkpatch.pl script has a special case to permit the following
operators to have no spaces around them:
 <<  >>  &  ^  |  +  -  *  /  %

QEMU style prefers all operators to consistently have spacing around
them, so remove this special case handling. This avoids reviewers
having to manually note it during code review.

I actually thought failing to point out the lack of spaces was
a checkpatch parsing bug until I looked in the source and found it
was deliberate...

I say "QEMU style prefers", but possibly what I actually mean is
"I prefer" ? Does anybody want to defend the unspaced versions?
