From 1debfb3315d95ab5ce328e307bd115b4400685fb Mon Sep 17 00:00:00 2001 From: Chase Douglas Date: Mon, 30 Aug 2010 13:27:45 -0400 Subject: HID: debugfs: wake up reading tasks upon event Some devices poke the hid core in a way that causes hid_debug_event to be called, while never calling hid_dump_input. Without this wakeup addition, tasks reading for hid events through debugfs may never see any events. It may be that a well written driver doesn't cause this, but then what's the point of debugfs?
