(I wonder which of these, indirectly, pulls in <linux/module.h>.)

This alias seems only useful if there's a corresponding struct
platform_device. Ie, a struct platform_device with a .name of "spi
-lpc32xx", which will fire off a "MODALIAS=platform:spi-lpc32xx" uevent
when it's created.

I couldn't find that platform_device. Did I miss something? Or is there
another way this alias is useful?

Thanks,
