Subject: [PATCH v2 0/6] gpiolib: acpi: Refactor to shrink the code by ~8%

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.

add/remove: 0/2 grow/shrink: 0/5 up/down: 0/-1221 (-1221)

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()
