From c013f4111f36b0b4327e7fbf46c0dd93399e9209 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 10 Mar 2023 08:47:29 -0600 Subject: [PATCH] fbdev: Use of_property_present() for testing DT property presence It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
