Subject: [PATCH] staging: rtl8723au: multiple condition with no effect - if identical to else
Date: Tue,  3 Feb 2015 08:08:16 -0500	[thread overview]
Message-ID: <1422968896-26562-1-git-send-email-hofrat@osadl.org> (raw)

A number if/else if/else branches are identical - so the condition has no
effect on the effective code and can be significantly simplified - this 
patch removes the condition and the duplicated code.

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

This looks like the output of some broken code-generator - unlikely someone
wrote this by hand. In any case it needs a review by someone that knows the
details of the driver. 

Anyway the number of useless code repetition is potentially record breaking !

Patch was compile tested for x86_64_defconfig + CONFIG_STAGING=y
CONFIG_R8723AU=m, CONFIG_8723AU_BT_COEXIST=y

Patch is against 3.0.19-rc7 (localversoin = -next-20150203)
