Subject: [PATCH 4.14 135/229] video: fbdev: sis: fix typos in SiS_GetModeID()

From: Rustam Subkhankulov <subkhankulov@...ras.ru>

[ Upstream commit 3eb8fccc244bfb41a7961969e4db280d44911226 ]

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.
