I'm also getting on the OMAP4430SDP:

Error setting wl12xx data

What a wonderfully descriptive error message. Not. What happened to
saying _why_ we couldn't set the data? As for this:

platform_device_register(&omap_vwlan_device);

and not checking the return code, I really don't see why anyone bothered
even reporting that wl12xx_set_platform_data() failed... why not just
leave people in the dark over the error...

Right, so, this "error" is happening because the WL12xx driver is not
configured, and from what I can see, the WL12xx is something you'd plug
in to the board instead of the SD card. So it makes no sense to report
an error for a driver for a bit of hardware which is optional.

So... my patch gets larger and gets this fixed for all platforms in
mach-omap2.

PRCM: failed to allocate irq descs: -12

Does OMAP require sparse IRQ, or is NR_IRQS not set sufficiently high for
OMAP? I can't work this one out, and it looks like things are missing for
this to even work (did something in plat/irqs.h get missed?)
