From fa0ecbb9905d985a77e76801ba1153394ba593e8 Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Thu, 27 Feb 2014 19:35:12 -0800 Subject: mwifiex: remove global variable cmd_wait_q_required There is a race condition while queuing synchronous command and asynchronous command requested from different threads, because the wait_q_enabled flag is set based on a global variable cmd_wait_q_required. The issue is fixed by removing this global variable and using a unified function with an argument 'sync' passed into the function.
