From 747a562f342895bbb6cfdfcb82104b4b2ae566e6 Mon Sep 17 00:00:00 2001 From: John Hughes Date: Wed, 16 Nov 2011 19:51:57 +0100 Subject: to fix scancodes returned by sony-laptop driver Fix scancodes returned by driver to match scancodes used to remap keys. (Before the patch FN/E returned scancode 0x1B, but to remap scancode 0x14 had to be used). The scancodes returned by the sony-laptop driver for function keys did not match the scancodes used to remap keys. Also, since the scancode was sent to the input subsystem after the mapped keysym the /lib/udev/keymap utility was confused about which scancode to report for which keysym. This patch fixes the driver so the correct scancode is shown for each key. It also adds to the documentation a description of where to find the scancodes.
