usb: dwc3: gadget: Move vbus draw to workqueue context
[ Upstream commit 54aaa3b387c2f580a99dc86a9cc2eb6dfaf599a7 ]
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.
Fixes: 99288de36020 ("usb: dwc3: add an alternate path in vbus_draw callback")
