Subject: [PATCH v1 1/2] gpiolib: acpi: Add fwnode name to the GPIO interrupt label
Date: Wed, 17 Apr 2024 13:37:27 +0300

It's ambiguous to have a device-related index in the GPIO interrupt
label as most of the devices will have it the same or very similar.
Extend label with fwnode name for better granularity. It significantly
reduces the scope of searching among devices.
