PATCH 1/1 driver core patch against 2.6.26-rc4

Here is a single patch against your 2.6.26-git tree.

It was suggested by Stephen, as it will help with the linux-next merge issues starting to happen as this api changes in anticipation for 2.6.27. This patch merges a functional version of the dev_set_name() function for other trees to be able to take adnd merge in changes that help with the progression toward getting rid of the bus_id field and the limitation of 20 characters for the name of struct device.

Please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6.git/

The patch will be sent as a follow-on to this message to lkml for people to see.

thanks,

greg k-h

PATCH 1/1 driver-core: prepare for 2.6.27 api change by adding dev_set_name

From: Stephen Rothwell <[email protected]>

Create the dev_set_name function now so that various subsystems can start changing over to it before other changes in 2.6.27 will make it compulsory.
