Sure I can do that, however, could you comment on Ming's comments?  Is
this patchset something we find useful at the moment as regards listing
and/or updating the firmware path list.

That patch is here:
	http://opensource.wolfsonmicro.com/~dp/patches/firmware/0004-firmware-Add-write-support-to-proc-fw_path.patch

However I've not rebased that patch on top of linux-next and I did not
send it for review as it seems that it may be a more sensible solution
to pass this as a kernel parameter.

Let me know what you think and I'll squeeze some time this weekend
to look at this.

Thanks,
Dimitris
