Subject: [PATCH v2 4/8] platform/x86: intel_skl_int3472: Use ACPI GPIO resource directly
When we call acpi_gpio_get_io_resource(), the output will be
the pointer to the ACPI GPIO resource. Use it directly instead of
dereferencing the generic resource.
Signed-off-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
