From d2bfac009ca2ea75befe5adde9ba8fd46e409c91 Mon Sep 17 00:00:00 2001 From: Glen Lee Date: Thu, 24 Sep 2015 18:15:04 +0900 Subject: [PATCH] staging: wilc1000: remove mutex txq_cs and it's related codes mutex txq_cs is never used in the driver. txq_cs, txq_critical_section and txq_lock have same pointer so just delete them and it's related codes.
