From 8750ab6236b0f54db4be6406bb2a4a71f908f049 Mon Sep 17 00:00:00 2001 From: Xinming Hu Date: Wed, 14 Dec 2016 19:40:47 +0530 Subject: [PATCH] mwifiex: get rid of mwifiex_do_flr wrapper This patch gets rid of mwifiex_do_flr. We will call mwifiex_shutdown_sw() and mwifiex_reinit_sw() directly. These two general purpose functions will be useful for sdio card reset handler.
