From a4722fd3f2d3590af5200890b61dbbdf87480abb Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 20 Nov 2014 10:12:32 -0600 Subject: [PATCH] usb: dwc3: trace: don't save pointers There was another instance where we were holding pointers which could be long gone. Fix that by caching only values pointed to by such pointer. Because no crash has been observed, this patch will be sent on v3.19 merge window, instead of -rc.
