From e9c8862f19958846dd0c7b39d0f6216aad6c7bee Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Thu, 6 Jul 2006 00:20:47 -0400 Subject: Input: remove accept method from input_dev This method used to enforce exclusive access to iforce devices, but presenlty there are no known users of this method.

This will allow input handlers to re-synchronize state of once-grabbed device with the rest of 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.
