Subject: [PATCH 1/2] staging: rtl8188eu: odm: condition with no effect

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.

The if/else performing the same settings in both branches so the
condition has no effect.

This needs a check by someone who knows the details of the driver
as it could be that the two branches actually should be different.

Patch was only compile-tested for x86_64_defconfig + CONFIG_STAGING=y
CONFIG_R8188EU=m

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

Subject: [PATCH 2/2] staging: rtl8188eu: odm: conditional setting with no effect

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. Due to this being a fall-through-if here - the first
if condition has no effect either - so it also can be removed.
struct mlme_priv is thus also no longer needed here.

>From the comments it seems that an effect is actually intended so this
may be a bug.
