[Qemu-devel] [PATCH] usb: Fix usb-bt-dongle segfault.

[Hani Benhabiles <kroosec@gmail.com>]

Due to an incomplete initialization, adding a usb-bt-dongle device through HMP
or QMP will cause a segmentation fault.

Not sure about the exact policy of qemu-stable. CC'ing it as this bug results in
a segfault.
