usb: dwc3: gadget: simplify next_request() return check
In dwc3_cleanup_done_reqs() we expect that all
iterations of our while (1) loop will find a valid
struct dwc3_request *. In case we don't, we're
dumping a WARN_ON_ONCE() splat so that people report
the failure.
This patch is a simple cleanup converting:
if (!req) {
WARN_ON_ONCE(1);
return 1;
}
to:
if (WARN_ON_ONCE(!req))
return 1;
which is a little easier to read.
