Return-Path: From: Amitkumar Karwar To: CC: Cathy Luo , Nachiket Kukade , Amitkumar Karwar Subject: [PATCH 1/2] Bluetooth: btmrvl: fix firmware dump issue Date: Fri, 18 Sep 2015 06:40:40 -0700 Message-ID: <1442583641-3182-1-git-send-email-akarwar@marvell.com> MIME-Version: 1.0 Content-Type: text/plain Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Nachiket Kukade First firmware dump attempt from user works fine, but firmware goes into bad state after this. Subsequent attempts fails. As required by the firmware dump implementation, this change writes FW_DUMP_READ_DONE value to dump ctrl register to address this issue.
