From a4c1cbc7819e890d4c2bc2b79b6cbf0fd9cad699 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 29 Aug 2009 22:03:47 -0300 Subject: V4L/DVB (12600): dvb-usb-remote: return KEY_RESERVED if there's free space for new keys The input subsystem checks if get_keycode works for a scan code. Due to that, we need to return a valid value when there's some space at the table that can be used by a scancode.
