From 73ee4da994e7b97bd8241e39099cf3dd94675d79 Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Tue, 5 Apr 2011 18:36:38 +0300 Subject: [PATCH] usb: gadget: f_mass_storage: Fix Bulk-only RESET handling The ep0 request tag was not recorded thus resulting in phase problems while sending status/response in handle_execption() handler. This was resulting in MSC compliance test failures with USBCV tool. With this patch, the Bulk-Only Mass storage RESET request is handled correctly and the MSC compliance tests pass.
