Subject: [PATCH v1 04/12] ArmPkg: Fix Non-Boolean comparison in ArmGicEnableDistributor
Date: Tue, 23 May 2023 14:04:13 +0100 [thread overview]
Message-ID: <20230523130421.10804-5-sami.mujawar@arm.com> (raw)
In-Reply-To: <20230523130421.10804-1-sami.mujawar@arm.com>
According to edk2 coding standard specification, Non-Boolean
comparisons must use a compare operator (==, !=, >, < >=, <=).
See Section 5.7.2.1 at https://edk2-docs.gitbook.io/
edk-ii-c-coding-standards-specification/5_source_files/
57_c_programming
Therefore, fix the comparison in ArmGicEnableDistributor()
