From 475b9eacc5543eea922431bb8ac4ec761de0e415 Mon Sep 17 00:00:00 2001 From: Nachiket Kukade Date: Fri, 18 Sep 2015 06:40:40 -0700 Subject: [PATCH] Bluetooth: btmrvl: fix firmware dump issue 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.
