From f8acb08d8a1b2edab352430bd32c0e694bc65bc5 Mon Sep 17 00:00:00 2001 From: Anton Tikhomirov Date: Thu, 21 Apr 2011 17:06:42 +0900 Subject: [PATCH] USB: s3c-hsotg: Fix hang up after reset When File Storage gadget receives SET CONFIGURATION request it tries to cancel all pending transfers. If some request is in progress, gadget waits for its completion. This commit allows gadget to dequeue invalid requests in progress left after reset.
