svn commit: r193752 - head/sys/dev/kbdmux

[Ed Schouten]

Author: ed
Date: Mon Jun  8 20:24:29 2009
New Revision: 193752
URL: http://svn.freebsd.org/changeset/base/193752

Log:
  Use proper types in kbdmux_kbd_getc():
  
  - The return value should be a signed integer, because -1 means failure.
  - The c variable should be unsigned, to force it to be zero-extended
    when returned.
