Subject: [PATCH 10/13] rtlwifi: btcoex: 23b 2ant: let bt transmit when hw initialisation done
Date: Tue,  4 Apr 2017 11:50:03 -0500	[thread overview]
Message-ID: <20170404165006.14329-11-Larry.Finger@lwfinger.net> (raw)
In-Reply-To: <20170404165006.14329-1-Larry.Finger@lwfinger.net>

From: Yan-Hsuan Chuang <yhchuang@realtek.com>

During hw initialisation, wifi may be ready after bt has already been
ready, which causes bt to act abnormally. To avoid this, set GNT_BT to
high during hw init.
