From 369d3c439a39dea6020e3a5ae25821b0832822da Mon Sep 17 00:00:00 2001 From: Stephen Warren <swarren@nvidia.com> Date: Tue, 1 Jul 2014 16:59:08 -0600 Subject: [PATCH] USB: gadget: atmel: zero out allocated requests A UDC's alloc_request method should zero out the newly allocated request. Ensure the Atmel driver does so. This issue was found by code inspection, following the investigation of an intermittent issue with ci_udc, which was tracked down to failing to zero out allocated requests following some of my changes. All other UDC drivers already zero out requests in one way or another.
