From fadadb7d7ad1d6c09863fcf24f83e59f596201ed Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Sun, 22 Mar 2009 23:42:26 -0300 Subject: [PATCH] V4L/DVB (11142): au0828: fix oops on ARM platform when allocating transfer buffers Add missing URB_NO_TRANSFER_DMA_MAP flag, since the use of consistent memory is not permitted for DMA on the ARM platform. Thanks to Paul Thomas for providing sample ARM hardware that was experiencing the oops (tested on the at91rm9200 based LinuxStamp). Thanks to David Brownell for providing insight into the ARM memory architecture.
