[PATCH 06/12] drm/sprd: move to devm_platform_ioremap_resource() usage
From: Anusha Srivatsa <hidden>
Date: 2025-02-05 20:10:29
Also in:
dri-devel, imx, linux-doc, linux-mediatek, linux-rockchip, linux-tegra, lkml
Subsystem:
drm drivers, drm drivers and misc gpu patches, the rest · Maintainers:
David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Linus Torvalds
Replace platform_get_resource + devm_ioremap
with just devm_platform_ioremap_resource()
Used Coccinelle to do this change. SmPl patch:
@rule_2@
identifier res;
expression ioremap;
identifier pdev;
@@
-struct resource *res;
...
-res = platform_get_resource(pdev,...);
<...
-if (!res) {
-...
-}
...>
-ioremap = devm_ioremap(...);
+ioremap = devm_platform_ioremap_resource(pdev,0);
