[PATCH 2/2] gpio / ACPI: Use local variable instead of ACPI_HANDLE()

From: Rafael J. Wysocki
Date: Tue Mar 10 2015 - 17:46:35 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

In acpi_gpiochip_request_interrupts() the handle local
variable already contains the value that we want to pass
to acpi_walk_resources(), so it is better to use that
variable instead of evaluating ACPI_HANDLE() once more
for the same device.
