Subject: dma_ops->map_page == NULL
Date: Mon, 6 Jul 2009 17:51:00 +0000 [thread overview]
Message-ID: <4A523984.2080904@marel.com> (raw)
I am doing a driver that uses dma_map_single().
After changing to to linux 2.6.29.3 I am getting
segfaults in dma_map_single() because dma_ops->map_page is NULL.
Actually dma_ops looks funky too.
The driver is an of_platform_driver which is declared as an child of
the lbp (fsl,lpb) node of the device tree.
This is on powerpc 5200b platform.
