In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: gadget: Move vbus draw to workqueue context
Currently dwc3_gadget_vbus_draw() can be called from atomic
context, which in turn invokes power-supply-core APIs. And
some these PMIC APIs have operations that may sleep, leading
to kernel panic.
Fix this by moving the vbus_draw into a workqueue context.
