When polled input device is opened and closed and there are no other users of polled device, the workqueue is created and destroyed in every open / close operation. It is probable that at some point dynamic allocation of internal parts of the workqueue cause changes to the workqueue. When a work is queued to the workqueue the work struct contains pointers to the workqueue data. If the workqueue has been changed and the work has never been queued to the new workqueue, work-struct contains pointers to the non-existing workqueue. This will cause crash at the work cancellation during device close since cancellation of a work assumes that the workqueue exists. To prevent that, work struct is cleaned up at device close. This keeps work struct clean for the next use. Signed-off-by: NSamu Onkalo <samu.p.onkalo@nokia.com> Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

More and more devices choose to reimplement support for sparse keymaps first introduced by wistron driver. Move it into a library module so it can be easily used by interested parties. Reviewed-by: NAnisse Astier <anisse@astier.eu> Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

If the poll interval is set to 0 via new sysfs entry and device is opened after that, polling is started with interval 0. This causes huge CPU load. Same happens if the rate was 0 when the device was closed and then reopened. Signed-off-by: NSamu Onkalo <samu.p.onkalo@nokia.com> Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

It does not make sense to wait poll_interval before performing first read after opening the device, schedule the read immediately instead. Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

Sysfs entry for reading and setting of the polling interval. If the interval is set to 0, polling is stopped. Polling is restarted when interval is changed to non-zero. sysfs entries: poll = current polling interval in msec (RW) max = max allowed polling interval (RO) min = min allowed polling interval (RO) Minimum and maximum limit for interval can be set while setting up the device. Interval can be adjusted even if the input device is not currently open.

Everyone should be using input_{get|set}_drvdata() by now. Alias them to dev_{get|set}_drvdata() and remove ->private. Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

Rounding doesn't matter for the first tick, but we want succeeding ticks to be aligned on second boundary if poll interval is large enough. Also: cancel_rearming_delayed_workqueue is marked as obsolete in workqueue.h so use cancel_delayed_work_sync.
