[PATCH] Register AC97 Controller Reference with the platform bus
From: Grant Likely <hidden>
Date: 2007-11-07 16:15:24
From: Joachim Foerster <redacted> Add AC97 platform bus registration for Xilinx Virtex platforms. Signed-off-by: Joachim Foerster <redacted> Signed-off-by: Grant Likely <redacted> --- Josh, can you please pick up this patch into your .24 queue. I know it's arch/ppc, but it is harmless and it is required to get the AC97 device driver working on Virtex boards. It's pretty much a bug fix in that regard.
