Title
Bluetooth: btmtk: adjust the position to init iso data anchor
Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtk: adjust the position to init iso data anchor MediaTek iso data anchor init should be moved to where MediaTek claims iso data interface. If there is an unexpected BT usb disconnect during setup flow, it will cause a NULL pointer crash issue when releasing iso anchor since the anchor wasn't been init yet. Adjust the position to do iso data anchor init.
