HID: Only dump input if someone is listening
Going through the motions of printing the debug message information takes a long time; using the keyboard can lead to a 160 us irqsoff latency. This patch skips hid_dump_input() when there are no open handles, which brings latency down to 100 us. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
