Subject: [PATCH RFC] video: fbdev: sis: condition with no effect
Date: Wed,  4 Feb 2015 06:36:14 -0500	[thread overview]
Message-ID: <1423049774-16305-1-git-send-email-hofrat@osadl.org> (raw)

The if and the else branch code are identical - so the condition has no
effect on the effective code - this patch removes the condition and the
duplicated code.

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>
---

This code has been in here since commit 544393fe584d ("sisfb update") so I guess it is
safe to simply remove the duplicated code if nobody noticed for 10 years.

Note that the code is not really CodingStyle compliant - the lines inserted were formatted
to satisfy the coding style but I'm unsure if it is not better to leave it in the
old format.

Patch was only compile tested with x86_64_defconfig +
CONFIG_FB_SIS=m, CONFIG_FB_SIS_300=y, CONFIG_FB_SIS_315=y

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
