From 3977a6477dd1e53fac2016a719a3c2cb2cdba771 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Mon, 14 Apr 2014 15:32:55 -0700 Subject: [PATCH] mwifiex: remove redundant 'fw_load' completion structure 'add_remove_card_sem' semaphore already takes care of synchronization for driver load and unload threads. Hence there won't be a case when unload thread is waiting on 'wait_for_completion(fw_load)'. Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
