From 3a48b38f48433accfc4e90409d88b9876ed74c8a Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 12 Jan 2025 14:46:34 +0100 Subject: [PATCH] fbdev: omapfb: Use syscon_regmap_lookup_by_phandle_args 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. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data. Dtschema and Devicetree bindings offer the static/build-time check for this already.
