From: Simon Glass Date: Wed, 21 Dec 2022 23:08:15 +0000 (-0700) Subject: trace: Use notrace for short X-Git-Tag: v2023.07~193^2~37 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=33c60a38bb95c9954704857fe5edb29b749b9b18;p=platform%2Fkernel%2Fu-boot.git trace: Use notrace for short The attribute syntax is quite verbose. Use the macro provided for this purpose.
