ACPI: clean up video.c boundary checks and types
proc.c and video.c are a bit sloppy around types and style,
confusing gcc for a new feature that'll be in 2.6.33 and will
cause a warning on the current code.
This patch changes
if (foo + 1 > sizeof bar)
into
if (foo >= sizeof(bar))
which is more kernel-style.
it also changes a variable in proc.c to unsigned; it gets assigned
a value from an unsigned type, and is then only compared for > not
for negative, so using unsigned is just outright the right type
