Subject: [RESEND] powerpc: rackmeter: Fix module autoload for OF platform driver

From: Luis de Bethencourt <luis@...ethencourt.com>

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Hi,

This is a resend of a patch sent September 17 [0]

Adding Andrew Morton to the CC list, as recommended at Korea Linux Forum.

This patch adds the missing MODULE_DEVICE_TABLE() for OF to export
that information so modules have the correct aliases built-in and
autoloading works correctly.

A longer explanation by Javier Canillas can be found here:

Thanks,
Luis
