In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: Fix the memory leak in raw_gadget driver
Currently, increasing rawdev->count happens before invoke the rawqueueevent(), if the rawqueueevent() return error, invoke rawrelease() will not trigger the dev_free() to be called.

This commit therefore invoke krefget() under the condition that rawqueue_event() return success.
