2006-11-02Input: add comments to input_{allocate|free}_device()Dmitry Torokhov
Hopefully this will stop people from using input_free_device() incorrectly. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-09-14Input: make input_register_handler() return error codesDmitry Torokhov
Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-09-14Input: remove cruft that was needed for transition to sysfsDmitry Torokhov
Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-09-14Input: fix input module refcountingDmitry Torokhov
Now that input_free_device is basically an alias for input_put_device we need to acquire a reference to input module right when we allocate device because input_dev_release releases reference to input module unconditionally. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-09-14Input: constify input coreDmitry Torokhov
Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-09-10Input: send key up events at disconnectDmitry Torokhov
Emit key up events for all pressed keys/buttons when disconnecting an input device. Cures "stuck" enter key effect when unloading keyboard module. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-07-19Input: implement new force feedback interfaceAnssi Hannula
Implement a new force feedback interface, in which all non-driver-specific operations are separated to a common module. This includes handling effect type validations, locking, etc. The effects are now file descriptor specific instead of the previous strange half-process half-fd specific behaviour. The effect memory of devices is not emptied if the root user opens and closes the device while another user is using effects. This is a minor change and most likely no force feedback aware programs are affected by this negatively. Otherwise the userspace interface is left unaltered.

2006-07-19Input: add missing handler->start() callDmitry Torokhov
The start() method need to be called every time we create a new handle. This includes not only registering new devices but also when registering new handlers. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-07-15Input: fix list iteration in input_release_device()Andrew Morton
Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-07-06Input: introduce input_inject_event() functionDmitry Torokhov
Create input_inject_event() function which is to be used by input handlers as opposed to input_event() which is reserved for drivers implementing input devices. The difference is that if device is "grabbed" by some process input_inject_event() will ignore events unless sent from the handle that is currently owns the device. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-07-06Input: add start() method to input handlersDmitry Torokhov
The new start() method is called immediately after connect() and also when "grabbed" device is released by its owner. This will allow input handlers to re-synchronize state of once-grabbed device with the rest of devices. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-07-06Input: remove accept method from input_devDmitry Torokhov
This method used to enforce exclusive access to iforce devices, but presenlty there are no known users of this method. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-06-27Input: fix resetting name, phys and uniq when unregistering deviceDmitry Torokhov
It should be done before calling class_device_unregister() because it will destroy the device and free memory if there are no other references to the device. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-26Input: rearrange exportsDmitry Torokhov
New style is to mark symbol as exported right after its definition. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-06-26Input: fix formatting to better follow CodingStyleDmitry Torokhov
Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-06-26Input: reset name, phys and uniq when unregisteringDmitry Torokhov
Name, phys and uniq are quite often constant strings in moules implementing particular input device. If a module unregisters input device and then gets unloaded, the device could still be present in memory (pinned via sysfs), but aforementioned members would point to some random memory. Set them all to NULL when unregistering so sysfs handlers won't try dereferencing them. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-06-26Input: return correct size when reading modalias attributeRichard Purdie

Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2006-04-02Input: limit attributes' output to PAGE_SIZEDmitry Torokhov
sysfs can't handle more than PAGE_SIZE data coming from attributes' show() methods; make sure we respect this limit. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Mark the f_ops members of inodes as const, as well as fix the ripple-through this causes by places that copy this f_ops and then "do stuff" with it.

2006-01-04[PATCH] Input: add modalias supportRusty Russell
Here's the patch for modalias support for input classes. It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.

2006-01-04[PATCH] driver core: replace "hotplug" by "uevent"Kay Sievers
Leave the overloaded "hotplug" word to susbsystems which are handling real devices. The driver core does not "plug" anything, it just exports the state to userspace and generates events. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-04[PATCH] remove CONFIG_KOBJECT_UEVENT optionKay Sievers
It makes zero sense to have hotplug, but not the netlink events enabled today. Remove this option and merge the kobject_uevent.h header into the kobject.h header file. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
