From e5b06c077c592e7e1623641520787a3da7b7c6bf Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Wed, 28 Jul 2010 15:50:00 +0200 Subject: [PATCH] firewire: ohci: release channel in error path firewire-ohci keeps book of which isochronous channels are occupied by IR DMA contexts, so that there cannot be more than one context listening to a certain channel. If IR context creation failed due to an out-of-memory condition, this bookkeeping leaked a channel.
