[PATCH] tms380tr: move to DMA API
This patch makes tms380tr use the new DMA API. Now that on Alpha, this API also supports bus master DMA for ISA (platform) devices, i changed the driver to use this new API. This also works around a bug in the firmware loader: The example provided in Documentation/firmware_class no longer works, as the firmware loader now calls get_kobj_path_length() and the kernel promptly oopses, as the home-grown device doesn't have a parent. Of course, this doesn't happen with a "real" device which has its bus (or pseudo bus in the case of platform) as parent. Converted tms380tr to use new DMA API: - proteon.c, skisa.c: use platform pseudo bus to create a struct device - Space.c: delete init hooks - abyss.c, tmspci.c: pass struct device to tms380tr.c - tms380tr.c, tms380tr.h: new DMA API, use real device fo firmware loader Signed-off-by: Jochen Friedrich <jochen@scram.de> Cc: Jeff Garzik <jgarzik@pobox.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
