From: Ron Rindjunsky Date: Mon, 30 Jun 2008 09:23:13 +0000 (+0800) Subject: iwlwifi: remove obsolete lq_ready use X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=36e1f16ed293d47f052f3532f2fc74c1bfe9c09e;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git iwlwifi: remove obsolete lq_ready use This patch removes the use of lq_ready, once used to sync between link quality commands to avoid race conditions, but no longer needed as bss_info_changed is in use.
