## Description

In the Linux kernel, the following vulnerability has been resolved:  media: uvcvideo: Fix deadlock if uvc_status_stop is called from async_ctrl.work  If a UVC camera has an asynchronous control, uvc_status_stop may be called from async_ctrl.work:  uvc_ctrl_status_event_work()     uvc_ctrl_status_event()         uvc_ctrl_clear_handle() 	    uvc_pm_put() 	        uvc_status_put() 		    uvc_status_stop() 		        cancel_work_sync()  This will cause a deadlock, since cancel_work_sync will wait for uvc_ctrl_status_event_work to complete before returning.  Fix this by returning early from uvc_status_stop if we are currently in the work function. flush_status now remains false until uvc_status_start is called again, ensuring that uvc_ctrl_status_event_work won't resubmit the URB.
