ACPI / sysfs: Treat the count field of counter_show() as unsigned
The count field is an unsigned 32bit value, and the counter_show() function should also treat it as a unsigned value. Otherwise the counter may show negative number as we found on a machine: ... gpe23: 0 invalid gpe24: -2071733 enabled gpe25: 0 invalid ... gpe_all: -2070980 sci: -2070949 Signed-off-by: Nan Li <nli@suse.com> Signed-off-by: Lee, Chun-Yi <jlee@suse.com> Signed-off-by: Rafael J.
