From 486e2df6ce213d0c776befdf3fe5ffc61dd61688 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Tue, 24 May 2005 17:51:52 -0700 Subject: [PATCH] [PATCH] USB gadget: drain rndis response queue on disconnect Drain the rndis response queue on disconnect. This fixes a problem in which an rndis response left in the queue from a previous session could cause a subsequent session to fail.
