From: Markus Armbruster Date: Tue, 20 Jul 2021 12:53:53 +0000 (+0200) Subject: error: Use error_fatal to simplify obvious fatal errors (again) X-Git-Tag: v6.2.0-rc0~130^2~14 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f9734d5d4078f17daf328b9e113aaffe3d00ecaf;p=thirdparty%2Fqemu.git error: Use error_fatal to simplify obvious fatal errors (again) We did this with scripts/coccinelle/use-error_fatal.cocci before, in commit 50beeb68094 and 007b06578ab. This commit cleans up rarer variations that don't seem worth matching with Coccinelle.
