From: Yang Li Date: Tue, 14 Mar 2023 08:02:30 +0000 (+0800) Subject: drm/arm/hdlcd: Use devm_platform_ioremap_resource() X-Git-Tag: v6.4-rc1~162^2~19^2~46 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=06bc8c80cba8347c3f459d276cfbd75ea0bbb6d1;p=thirdparty%2Fkernel%2Flinux.git drm/arm/hdlcd: Use devm_platform_ioremap_resource() According to commit 7945f929f1a7 ("drivers: provide devm_platform_ioremap_resource()"), convert platform_get_resource(), devm_ioremap_resource() to a single call to Use devm_platform_ioremap_resource(), as this is exactly what this function does. Since 'struct platform_device *pdev = to_platform_device(drm->dev)', 'drm->dev' is equivalent to 'pdev->deva'.
