From 1144601118507f8b3b676a9a392584d216d3f2cc Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 6 Apr 2010 12:05:01 -0700 Subject: [PATCH] ath9k: fix double calls to ath_radio_enable With the enable_radio being uninitialized, ath_radio_enable() might be called twice, which can leave some hardware in an undefined state.
