From 149fc35734e50fc3200cf84c8efd711205961636 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 12 Jan 2025 14:39:03 +0100 Subject: PCI: layerscape: Use syscon_regmap_lookup_by_phandle_args MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier.
