Subject: [RESEND] [PATCH 2/3] Bluetooth: btusb: Load firmware exclusively for Intel BT
Date: Wed, 3 Oct 2018 15:35:55 +0800 [thread overview]
Message-ID: <20181003073556.28154-2-kai.heng.feng@canonical.com> (raw)
In-Reply-To: <20181003073556.28154-1-kai.heng.feng@canonical.com>
To avoid the firmware loading race between Bluetooth and WiFi on Intel
8260, load firmware exclusively when IWLWIFI is enabled.
