[PATCH v3 13/13] video: fbdev: sis: Drop useless call to SiS_GetResInfo()

From: Sam Ravnborg <hidden>
Date: 2020-12-06 19:05:56
Also in: dri-devel, linux-arm-kernel
Subsystem: framebuffer layer, sis framebuffer driver, the rest · Maintainers: Helge Deller, Linus Torvalds

Coverity reported:

    Useless call (USELESS_CALL) side_effect_free: Calling
     SiS_GetResInfo(SiS_Pr, ModeNo, ModeIdIndex) is only useful for its
    return value, which is ignored.

And this is correct - so drop the call.
