From 310ddb638b7b5223eef1960c7704fee7b18d1bf6 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Sat, 29 Sep 2018 20:18:34 +0200 Subject: [PATCH] MdePkg/BaseSynchronizationLib GCC: fix whitespace and comments MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The "GccInline.c" files have some inconsistent whitespace, and missing (or incorrect) operand comments. Fix and unify them. This patch doesn't change behavior.
