A simple refactoring of the GPIO ACPI library parts to get an impressive
~8% code shrink on x86_64 and ~2% on x86_32. Also reduces a C code a bit.

In v2:
- renamed par to params (Mika, Bart)
Andy Shevchenko (6):
gpiolib: acpi: Improve struct acpi_gpio_info memory footprint
gpiolib: acpi: Remove index parameter from acpi_gpio_property_lookup()
gpiolib: acpi: Reduce memory footprint for struct acpi_gpio_params
gpiolib: acpi: Rename par to params for better readability
gpiolib: acpi: Reuse struct acpi_gpio_params in struct
acpi_gpio_lookup
gpiolib: acpi: Deduplicate some code in __acpi_find_gpio()
