Subject: [PATCH] gpiolib-acpi: Move acpi_dev_add_driver_gpios() et al to consumer.h
Mime-version: 1.0

Git-commit: 2838bf941b120ec846a3903db13e319368d51b08
Patch-mainline: v5.4-rc1
References: jsc#SLE-12730
The API, which belongs to GPIO library, is foreign to ACPI headers. Earlier
we moved out I²C out of the latter, and now it's time for
acpi_dev_add_driver_gpios() et al.
For time being the acpi_gpio_get_irq_resource() and acpi_dev_gpio_irq_get()
are left untouched as they need more thought about.
Note, it requires uninline acpi_dev_remove_driver_gpios() to keep purity of
consumer.h.
