Subject[patch] (re)implement setkeycode/getkeycode/kd_mksound/kbd_setrate via the input core
Hi!

You can import this changeset into BK by piping this whole message to:
'| bk receive [path to repository]' or apply the patch as usual.
'bk pull bk://linux-input.bkbits.net/linux-input' should work as well.

===================================================================

ChangeSet@1.514, 2002-08-25 15:21:22+02:00, vojtech@suse.cz
This (re)implements getkeycode/setkeycode, kbd_rate and kd_mksound
as functions interfacing to the input core. PC-Speaker handling is
moved to a separate file. Uinput is moved to a input/misc directory.
