From 40aa41fba348bc5bd19ff5bcf2b03d67bb01d1ce Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 18 Jan 2012 17:06:03 +0200 Subject: [PATCH] usb: dwc3: gadget: fix XferNotReady debug print Only bit 3 of the event status bitfield is valid and the others should not be considered. Make sure SW matches documentation on that case to avoid bogus debugging prints which would confuse an engineer.
