From f2df679b6c556fd3b0b7ffafea170f1679086455 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 9 Jun 2016 16:31:34 +0300 Subject: usb: dwc3: gadget: avoid while(1) in run_stop() instead of looping forever and forcing a return if timeout reaches zero, we can just use timeout and loop's break condition directly.
