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 Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
