create /sys/.../power when CONFIG_PM is set

2007-11-28T21:53:53+00:00

The CONFIG_SUSPEND changes in 2.6.23 caused a regression under certain
configuration conditions (SUSPEND=n, USB_AUTOSUSPEND=y) where all USB
device attributes in sysfs (idVendor, idProduct, ...) silently disappeared,
causing udev breakage and more.

The cause of this is that the /sys/.../power subdirectory is now only
created when CONFIG_PM_SLEEP is set, however, it should be created whenever
CONFIG_PM is set to handle the above situation.  The following patch fixes
the regression.

Driver Core: fix bug in device_rename() for SYSFS_DEPRECATED=y

2007-10-31T04:52:33+00:00

This should fix the sysfs warnings that renaming network devices is
causing to show up with CONFIG_SYSFS_DEPRECATED=y

The code just shouldn't run if class devices are real directories, it's
an update for the symlink in the class directory. Nobody noticed that as
long as the creation of sysfs files silently failed, and we both missed
it before the merge, because we don't run SYSFS_DEPRECATED=y.

Driver core: rename ktype_device

2007-10-12T21:51:12+00:00

This makes it a bit more sane when trying to figure out how to clean up
the ktype mess.

Driver core: exclude kobject_uevent.c for !CONFIG_HOTPLUG

2007-10-12T21:51:06+00:00

Move uevent specific logic from the core into kobject_uevent.c, which
does no longer require to link the unused string array if hotplug
is not compiled in.

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01+00:00

This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

Driver core: fix SYSF_DEPRECATED breakage for nested classdevs

2007-10-07T23:42:22+00:00

We should only reparent to a class former class devices that
form the base of class hierarchy. Nested devices should still
grow from their real parents.

Add explicit zeroing to "envp" array in device 'show' method

2007-09-26T16:16:21+00:00

As Stephen Hemminger says, this is a "belt and suspenders" patch that
zeroes the envp array at allocation time, even though all the users
should NULL-terminate it anyway (and we've hopefully fixed everybody
that doesn't do that).

And we'll apparently clean the whole envp thing up for 2.6.24 anyway.

But let's just be robust, and do both this *and* make sure that all
users are doing the right thing.

Driver core: fix deprectated sysfs structure for nested class devices

2007-09-19T18:24:18+00:00

Nested class devices used to have 'device' symlink point to a real
(physical) device instead of a parent class device.  When converting
subsystems to struct device we need to keep doing what class devices did if
CONFIG_SYSFS_DEPRECATED is Y, otherwise parts of udev break.

driver core: revert "device" link creation check

Commit 2ee97caf0a6602f749ddbfdb1449e383e1212707 introduced an extra
check on when to create the "device" symlink. Unfortunately, this
breaks input, so let's revert to the old behaviour.
