Subject: [PATCH 1/2] MdeModulePkg/Bus/Ata/AtaAtapiPassThru: Fix SIGN_EXTENSION Coverity issue
Date: Fri, 2 Jun 2023 12:39:45 +0530 [thread overview]
Message-ID: <20230602070946.83730-1-rsingh@ventanamicro.com> (raw)
From: Ranbir Singh <Ranbir.Singh3@Dell.com>
Line number 1348 does contain a typecast with UINT32, but it is after
all the operations (16-bit left shift followed by OR'ing) are over.
To avoid any SIGN_EXTENSION, typecast the intermediate result after
16-bit left shift operation immediately with UINT32.
