From caefe6c7be4778d0bddb38596ced1b60bd522b14 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Tue, 15 Nov 2016 13:05:23 +0200 Subject: [PATCH] usb: dwc3: gadget: use evt->length as we should Instead of always accessing the macro directly, let's rely on evt->length which is the actual length of current event buffer. While unlikely, we could change event buffer's size at any time.
