PATCH RESEND 1/1 drivers/char/keyboard.c unsigned comparison

keycode is a checked for a value less than zero, but is defined as an unsigned int, and is only called in one place in the kernel, and passed a unsigned int, so this comparison is bogus.

Thanks to LinuxICC (http://linuxicc.sf.net)

This patch applies to Linus' git tree as of 12.11.2005
