Driver core: Fix error handling in bus_add_driver().

2008-02-21T23:27:07+00:00

- If the allocation of ->priv fails, the reference on the bus
  must be dropped.
- If adding the kobject fails, kobject_put must be called to
  clean things up.

Driver core: add bus_find_device_by_name function

2008-01-27T23:01:39+00:00

The driver core, and some other parts of the kernel just want to find a
device based on a name for a specific bus.  Give them a simple wrapper
to prevent them from having to always roll their own.

This will be used in the PPC patch later in this series.

Driver core: coding style fixes

2008-01-25T06:50:12+00:00

Fix up a number of coding style issues in the drivers/base/ directory
that have annoyed me over the years.  checkpatch.pl is now very happy.

Kobject: convert drivers/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:40+00:00

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

Kobject: change drivers/base/bus to use kobject_init_and_add

2008-01-25T04:40:35+00:00

Stop using kobject_register, as this way we can control the sending of
the uevent properly, after everything is properly initialized.

Driver core: clean up debugging messages

2008-01-25T04:40:35+00:00

The driver core debugging messages are a mess.  This provides a unified
message that makes them actually useful.

The format for new kobject debug messages should be:
	driver/bus/class: 'OBJECT_NAME': FUNCTION_NAME: message.\n

Note, the class code is not changed in this patch due to pending patches
in my queue that this would conflict with.  A later patch will clean
them up.

Driver core: move the static kobject out of struct driver

2008-01-25T04:40:35+00:00

This patch removes the kobject, and a few other driver-core-only fields
out of struct driver and into the driver core only.  Now drivers can be
safely create on the stack or statically (like they currently are.)

driver core: remove fields from struct bus_type

2008-01-25T04:40:33+00:00

struct bus_type is static everywhere in the kernel.  This moves the
kobject in the structure out of it, and a bunch of other private only to
the driver core fields are now moved to a private structure.  This lets
us dynamically create the backing kobject properly and gives us the
chance to be able to document to users exactly how to use the struct
bus_type as there are no fields they can improperly access.

Thanks to Kay for the build fixes on this patch.

driver core: add way to get to bus device klist

2008-01-25T04:40:33+00:00

This allows an easier way to get to the device klist associated with a
struct bus_type (you have three to choose from...)  This will make it
easier to move these fields to be dynamic in a future patch.

The only user of this is the PCI core which horribly abuses this
interface to rearrange the order of the pci devices.  This should be
done using the existing bus device walking functions, but that's left
for future patches.
