From 6e6dd08dd3202d735143c973b888572955603391 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Sun, 1 Mar 2015 11:53:49 +0530 Subject: [PATCH] ath9k: Fix issues in the main btcoex timer * ath9k_mci_update_rssi() is required only for cards that use MCI scheme. Make sure that it is not called for 3-wire cards. * Call ath9k_ps_wakeup() early since register accesses are made in ath9k_mci_update_rssi(). * Fix usage of btcoex_lock to handle no_stomp_timer.
