From 3d44a6fd0775e6215e836423e27f8eedf8c871ea Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Thu, 14 Nov 2019 16:01:18 +0100 Subject: Bluetooth: btusb: fix PM leak in error case of setup If setup() fails a reference for runtime PM has already been taken. Proper use of the error handling in btusb_open()is needed. You cannot just return.
