From 4035cc15b99f4f4a4e29081b82aca010137e33da Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Fri, 21 Oct 2016 17:21:32 +0300 Subject: [PATCH] ACPI / gpio: Add support for naming GPIOs Now that we have the new helper function that sets nice names for GPIO lines based on "gpio-line-names" device property, we can take advantage of this in acpi_gpiochip_add().
