PATCH 2/11 staging: rtl8192e: Remove equation of local variable InactTime of AdmitTS

In reply to Philipp Hortmann

Remove equation of local variable InactTime of AdmitTS as AdmitTS is only once called with InactTime as 0. The equation is always false and therefore dead code.

PATCH 10/11 staging: rtl8192e: Remove variable priv->reg_chnl_plan

In reply to Philipp Hortmann

Remove variable priv->reg_chnl_plan as it is only once initialized and only once evaluated. So the result is always the same. Remove dead code.

PATCH 11/11 staging: rtl8192e: Remove variable ieee->short_slot

In reply to Philipp Hortmann

ieee->short_slot also named priv->rtllib->short_slot is initialized to 1 and then unchanged. All evaluations will result accordingly. Remove resulting dead code.
