Subject: [PATCH 11/14] drm/tegra: move to devm_platform_ioremap_resource() usage
Date: Tue, 28 Jan 2025 17:29:35 -0500	[thread overview]
Message-ID: <20250128-cocci-memory-api-v1-11-0d1609a29587@redhat.com> (raw)
In-Reply-To: <20250128-cocci-memory-api-v1-0-0d1609a29587@redhat.com>

Replace platform_get_resource + devm_ioremap_resource
with just devm_platform_ioremap_resource()

Used Coccinelle to do this change. SmPl patch:
@rule_1@
identifier res;
expression ioremap_res;
identifier pdev;
@@
-struct resource *res;
...
-res = platform_get_resource(pdev,...);
-ioremap_res = devm_ioremap_resource(...);
+ioremap_res = devm_platform_ioremap_resource(pdev,0);
