Driver core: Remove unneeded get_{device,driver}() calls.

2008-02-02T23:14:49+00:00

Driver core: Remove unneeded get_{device,driver}() calls.

Code trying to add/remove attributes must hold a reference to
the device resp. driver anyway, so let's remove those reference
count games.

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: rename kobject_add_ng() to kobject_add()

2008-01-25T04:40:38+00:00

Now that the old kobject_add() function is gone, rename kobject_add_ng()
to kobject_add() to clean up the namespace.

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: add driver_add_kobj for looney iseries_veth driver

2008-01-25T04:40:34+00:00

The iseries driver wants to hang kobjects off of its driver, so, to
preserve backwards compatibility, we need to add a call to the driver
core to allow future changes to work properly.

Hopefully no one uses this function in the future and the iseries_veth
driver authors come to their senses so I can remove this hack...

driver core: Introduce default attribute groups.

2008-01-25T04:40:34+00:00

This is lot like default attributes for devices (and indeed,
a lot of the code is lifted from there).

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.

kset: convert struct bus_device->drivers to use kset_create

2008-01-25T04:40:16+00:00

Dynamically create the kset instead of declaring it statically.

Having 3 static kobjects in one structure is not only foolish, but ripe
for nasty race conditions if handled improperly.  We also rename the
field to catch any potential users of it (not that there should be
outside of the driver core...)

Driver core: remove unneeded completion from driver release path

2007-04-27T17:57:29+00:00

The completion in the driver release path is due to ancient history in
the _very_ early 2.5 days when we were not tracking the module reference
count of attributes.  It is not needed at all and can be removed.

Note, we now have an empty release function for the driver structure.
This is due to the fact that drivers are statically allocated in the
system at this point in time, something which I want to change in the
future.  But remember, drivers are really code, which is reference
counted by the module, unlike devices, which are data and _must_ be
reference counted properly in order to work correctly.

driver core: do not wait unnecessarily in driver_unregister()

2007-04-01T17:54:13+00:00

Ingo reported that built-in drivers suffered bootup hangs with certain
driver unregistry sequences, due to sysfs breakage.

Do the minimal fix for v2.6.21: only wait if the driver is a module.
