Subject: gpio / ACPI: Use local variable instead of ACPI_HANDLE()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1ecb016e18149a1ea3de7dfd98f60b4b03e5e855;p=linux-beck.git

gpio / ACPI: Use local variable instead of ACPI_HANDLE()

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.
