[patch 14/30] floppy: provide a PNP device table in the module.

From: Greg KH
Date: Tue Jun 30 2009 - 20:33:53 EST


2.6.27-stable review patch. If anyone has any objections, please let us know.

------------------

From: Scott James Remnant <scott@xxxxxxxxxxxxx>

commit 83f9ef463bcb4ba7b4fee1d6212fac7d277010d3 upstream.

The missing device table means that the floppy module is not auto-loaded,
even when the appropriate PNP device (0700) is found.

We don't actually use the table in the module, since the device doesn't
have a struct pnp_driver, but it's sufficient to cause an alias in the
module that udev/modprobe will use.
