The rwsem is not used to protect anything, so the use of it by the PNP subsystem isn't really useful, and it's doubtful if it really did anything or not. So I've removed it. Cc: Adam Belay <ambx1@neo.rr.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

The driver core stopped using the rwsem a long time ago, yet the USB core still grabbed the lock, thinking it protected something. This patch removes that useless use.

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.

Don't fail bus_attach_device() if the device cannot be bound. If dev->driver has been specified, reset it to NULL if device_bind_driver() failed and add the device as an unbound device. As a result, bus_attach_device() now cannot fail, and we can remove some checking from device_add(). Also remove an unneeded check in bus_rescan_devices_helper().

Make multithreaded probing work per subsystem instead of per driver. It doesn't make much sense to probe the same device for multiple drivers in parallel (after all, only one driver can bind to the device). Instead, create a probing thread for each device that probes the drivers one after another. Also make the decision to use multi-threaded probe per bus instead of per device and adapt the pci code.

We get two per-bus sysfs files: ls-l /sys/subsystem/usb drwxr-xr-x 2 root root 0 2007-02-16 16:42 devices drwxr-xr-x 7 root root 0 2007-02-16 14:55 drivers -rw-r--r-- 1 root root 4096 2007-02-16 16:42 drivers_autoprobe --w------- 1 root root 4096 2007-02-16 16:42 drivers_probe The flag "drivers_autoprobe" controls the behavior of the bus to bind devices by default, or just initialize the device and leave it alone. The command "drivers_probe" accepts a bus_id and the bus tries to bind a driver to this device. Systems who want to control the driver binding with udev, switch off the bus initiated probing: echo 0 > /sys/subsystem/usb/drivers_autoprobe echo 0 > /sys/subsystem/pcmcia/drivers_autoprobe ... and initiate the probing with udev rules like: ACTION=="add", SUBSYSTEM=="usb", ATTR{subsystem/drivers_probe}="$kernel" ACTION=="add", SUBSYSTEM=="pcmcia", ATTR{subsystem/drivers_probe}="$kernel" ... Custom driver binding can happen in earlier rules by something like: ACTION=="add", SUBSYSTEM=="usb", \ ATTRS{idVendor}=="1234", ATTRS{idProduct}=="5678" \ ATTR{subsystem/drivers/<custom-driver>/bind}="$kernel" This is intended to solve the modprobe.conf mess with "install-rules", custom bind/unbind-scripts and all the weird things people invented over the years. It should also provide the functionality "libusual" was supposed to do. With udev, one can just write a udev rule to drive all USB-disks at the third port of USB-hub by the "ub" driver, and everything else by usb-storage. One can also instruct udev to bind different wireless drivers to identical cards - just selected by the pcmcia slot-number, and whatever ... To use the mentioned rules, it needs udev version 106, to be able to write ATTR{}="$kernel" to sysfs files. Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

As the new-style class devices (as opposed to old-style struct class_device) are becoming more widely used, I noticed that the dev_printk-based functions are not working properly with these. New-style class devices have no driver nor bus, almost by definition, and as a result dev_driver_string(), which is used as the first parameter of dev_printk, resolves to an empty string. This causes entries like the following to show in my logs: i2c-2: adapter [SMBus stub driver] registered Notice the unaesthetical leading whitespace. In order to fix this problem, I suggest that we extend dev_driver_string to deal with new-style class devices: Signed-off-by: NJean Delvare <khali@linux-fr.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>
