Subject: [PATCH] getkeycode: show reserved scancode
The scancode 0 is usually reserved. Hence the getkeycodes starts scanning at 1.
However, the scancode can still be used in some special cases, e.g. for a matrix
keypad with board specific combination of keycodes and scancodes. This one
change the scan range to start from 0.
probably not for mainline, as far kdb is maintained et all.
