Subject: checkpatch: improve "no space necessary after cast" test
X-Git-Tag: v5.15~16332^2~46
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=43f7fe52a82ec9f7aa6420af430745111674c7b9;p=platform%2Fkernel%2Flinux-starfive.git

checkpatch: improve "no space necessary after cast" test

Code like:
	if (a < sizeof(<type>) &&
and
	{ .len = sizeof(<type>) },

incorrectly emits that warning, so add more exceptions to avoid
the warning.
