From 600f5d909a54a8dccf8c8c23898fc2e91bc0953e Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Wed, 13 Apr 2011 17:27:06 -0700 Subject: [PATCH] mwifiex: cleanup ioctl wait queue and abstraction layer 1) remove mwifiex_alloc_fill_wait_queue() and mwifiex_request_ioctl() 2) avoid dynamic allocation of wait queue 3) remove unnecessary mwifiex_error_code macros that were used mainly by the wait queue status code 4) remove some abstraction functions 5) split mwifiex_prepare_cmd() to mwifiex_send_cmd_async() and mwifiex_send_sync() to handle asynchronous and synchronous commands respectively Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
