Input: initialize device counter variables with -1

2014-12-03T23:27:17Z

Let's initialize atomic_t variables keeping track of number of various devices created so far with -1 in order to avoid extra subtraction operation. Signed-off-by: Aniroop Mathur Signed-off-by: Dmitry Torokhov

Input: serio - avoid negative serio device numbers

2014-10-09T22:27:25Z

Fix the format string for serio device name generation to avoid negative device numbers when the id exceeds the maximum signed integer value. Signed-off-by: Richard Leitner Signed-off-by: Dmitry Torokhov

Input: serio - add firmware_id sysfs attribute

2014-04-20T05:42:19Z

serio devices exposed via platform firmware interfaces such as ACPI may provide additional identifying information of use to userspace. We don't associate the serio devices with the firmware device (we don't set it as parent), so there's no way for userspace to make use of this information. We cannot change the parent for serio devices instantiated though a firmware interface as that would break suspend / resume ordering. Therefore this patch adds a new firmware_id sysfs attribute so that userspace can get a string from there with any additional identifying information the firmware interface may provide.

Input: serio - fix sysfs layout

2013-12-10T06:23:26Z

Restore previous layout of sysfs attributes that was broken by commit 3778a2129bcce84f684cc0017ed20d2524afd289 (input: serio: remove bus usage of dev_attrs) which moved all serio device attributes into 'id' group, when only 'type', 'proto', 'id', and 'extra' should be in 'id' group and the rest of attributes should be attached directly to the device.

input: serio: remove bus usage of dev_attrs

2013-10-20T03:02:44Z

The dev_attrs field of struct bus_type is going away soon, so move the remaining sysfs files that are being described with this field to use dev_groups instead. Cc: Dmitry Torokhov Cc: Signed-off-by: Greg Kroah-Hartman

input: serio: use DEVICE_ATTR_RO()

2013-10-20T03:02:44Z

Convert the serio sysfs fiels to use the DEVICE_ATTR_RO() macros to make it easier to audit the correct sysfs file permission usage. Cc: Dmitry Torokhov Cc: Signed-off-by: Greg Kroah-Hartman

Input: serio: convert bus code to use drv_groups

2013-08-25T21:56:34Z

The drv_attrs field of struct bus_type is going away soon, drv_groups should be used instead. This converts the serio bus code to use the correct field. Acked-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: serio - remove CONFIG_HOTPLUG ifdefs

2012-11-24T08:03:39Z

Remove conditional code based on CONFIG_HOTPLUG being false. It's always on now in preparation of it going away as an option. Signed-off-by: Bill Pemberton Signed-off-by: Dmitry Torokhov

Driver core: driver_find() drops reference before returning

2012-01-25T00:00:34Z

As part of the removal of get_driver()/put_driver(), this patch (as1510) changes driver_find(); it now drops the reference it acquires before returning. The patch also adjusts all the callers of driver_find() to remove the now unnecessary calls to put_driver(). In addition, the patch adds a warning to driver_find(): Callers must make sure the driver they are searching for does not get unloaded while they are using it. This has always been the case; driver_find() has never prevented a driver from being unregistered or unloaded. Hence the patch will not introduce any new bugs. The existing callers all seem to be okay in this respect, however I don't understand the video drivers well enough to be certain about them.

Input: serio/gameport - use 'long' system workqueue

2011-02-23T16:53:07Z

Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio subsystem event handling from using a dedicated thread to using common workqueue. Unfortunately, this regressed our boot times, due to the fact that serio jobs take long time to execute. While the new concurrency managed workqueue code manages long-playing works just fine and schedules additional workers as needed, such works wreck havoc among remaining users of flush_scheduled_work(). To solve this problem let's move serio/gameport works from system_wq to system_long_wq which nobody tries to flush.
