SubjectPATCH: Spinlock Macro Arguments Correction in pc_keyb.c
I was compiling 2.5.1-pre3 this evening, and recieved errors to the effect of:
Line xxx:spinlock_unlock used with too many arguments
Line xxxx:spinlock_unlock_irqrestore used with too few arguments
Line XXXX:spinlock_unlock_irqrestore used with too few arguments

Not having ever done any serious kernel programming, I have only a dim
understanding of what spinlocks are, but by looking at those macro
definitions in spinlock.h (and their occurences elsewhere in the file) I
think I determined their proper usage. The following patch fixed the compile
errors, and I'm using 2.5.1-pre3 to type this message.

This is my first patch, so if I did anything wrong please correct me.
