[PATCH] Fix device_attribute memory leak in device_del

2006-11-25T21:28:33+00:00

dev->devt_attr is allocated in device_add() but it is never freed in
device_del() in the drivers/base/core.c file (reported by kmemleak).

Driver core: Don't ignore error returns from probing

2006-10-18T19:49:55+00:00

This patch (as797) fixes device_add() in the driver core.  It needs to
pay attention when the driver for a new device reports an error.

At the same time, since bus_remove_device() undoes the effects of both
bus_add_device() and bus_attach_device(), it needs to check whether
the bus_attach_device step failed.

Driver core: Don't leak 'old_class_name' in drivers/base/core.c::device_rename()

2006-10-18T19:49:55+00:00

If kmalloc() fails to allocate space for 'old_symlink_name' in
drivers/base/core.c::device_rename(), then we'll leak 'old_class_name'.

Spotted by the Coverity checker.

driver core fixes: device_add() cleanup on error

2006-10-18T19:49:55+00:00

Check for return code of device_create_file() and correct cleanup in
the error case in device_add().

Fix dev_printk() is now GPL-only

2006-10-18T19:49:54+00:00

Make dev_printk usable from non-GPL modules again

dev_printk now calls dev_driver_string.  We want even proprietary modules
to be calling dev_printk, so the export of dev_driver_string needs to be
non-GPL-only.

drivers/base: Platform notify needs to occur before drivers attach to the device

2006-09-26T04:08:39+00:00

The platform_notify call for Arm and PPC architectures needs to be called
before the driver attaches to the device.  The problem only presents itself
when hotplugging certain devices while the driver is already loaded.

Driver core: add ability for devices to create and remove bin files

2006-09-26T04:08:39+00:00

Makes it easier for devices to create and remove binary attribute files
so they don't have to call directly into sysfs.  This is needed to help
with the conversion from struct class_device to struct device.

Class: add support for class interfaces for devices

2006-09-26T04:08:38+00:00

When moving class_device usage over to device, we need to handle
class_interfaces properly with devices.  This patch adds that support.

Driver core: create devices/virtual/ tree

2006-09-26T04:08:38+00:00

This change creates a devices/virtual/CLASS_NAME tree for struct devices
that belong to a class, yet do not have a "real" struct device for a
parent.  It automatically creates the directories on the fly as needed.

Driver core: add device_rename function

2006-09-26T04:08:38+00:00

The network layer needs this to convert to using struct device instead
of a struct class_device.
