Summary
Bluetooth: btrtl: check for NULL in btrtl_set_quirks()
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btrtl: check for NULL in btrtlsetquirks()

The btrtlsetquirks() has accessed btrtldev->icinfo->lmp_subver since b8e482d02513. However, if installing a Realtek Bluetooth controller without the driver supported, it will hit the NULL point accessed.

Add a check for NULL to avoid the Kernel Oops.
