Subject: [PATCH] video/fbdev/sis: fix typos in SiS_GetModeID()
Date:   Mon, 18 Jul 2022 15:43:43 +0300
Message-Id: <20220718124344.46338-1-subkhankulov@ispras.ru>

Precedence: bulk

The second operand of a '&&' operator has no impact on expression
result for cases 400 and 512 in SiS_GetModeID().

Judging by the logic and the names of the variables, in both cases a
typo was made.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
