From adcad5364a692dac85e6e741bdce2a7609449ab8 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 29 Feb 2024 16:51:38 +0200 Subject: [PATCH] gpio: of: Make of_gpio_get_count() take firmware node as a parameter Make of_gpio_get_count() take firmware node as a parameter in order to be aligned with other functions and decouple from unused device pointer. The latter helps to create a common fwnode_gpio_count() in the future. While at it, rename to be of_gpio_count() to be aligned with the others.
