Subject: [PATCH] staging: r8188eu: remove some dead code
In this driver SupportICType is ODM_RTL8188E and SupportInterface is
ODM_ITRF_USB. Remove an if statement that is never true and remove
function odm_DIGbyRSSI_LPS() which is used only in this dead if block.
Signed-off-by: Michael Straube <straube.linux@...il.com>

Tested on x86_64 with Inter-Tech DMG-02.
