Also, replace the two locks in `bluetooth_radio` with `device_list_cs` instead.

New subject: [PATCH 2/2] winebth.sys: Fix potential deadlocks while performing operations that block on the DBus event loop.

From: Vibhav Pant vibhavp@gmail.com

Disconnecting and removing remote devices hold device_list_cs before blocking on the DBus event loop, which may cause a deadlock if we receive a message from BlueZ whose handler also attempts to enter device_list_cs (Like BLUETOOTH_WATCHER_EVENT_TYPE_DEVICE_PROPERTIES_CHANGED). To fix this, the device/radio handle is duplicated once found, device_list_cs is released, and the DBus method call is made using the duplicate handle(s), which are then freed normally. --- dlls/winebth.sys/unixlib.c | 16 ++++++++++++++ dlls/winebth.sys/unixlib.h | 12 ++++++++++ dlls/winebth.sys/winebluetooth.c | 18 +++++++++++++++ dlls/winebth.sys/winebth.c | 38 ++++++++++++++++++++++---------- dlls/winebth.sys/winebth_priv.h | 2 ++ 5 files changed, 74 insertions(+), 12 deletions(-)
