Subject: drm/tegra: vic: Use devm_platform_ioremap_resource()
X-Git-Tag: v6.1-rc5~617^2~14^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=135f4c551d51065ee2d0677bf5344a89767e9d9b;p=platform%2Fkernel%2Flinux-starfive.git

drm/tegra: vic: Use devm_platform_ioremap_resource()

Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately. Make the
code simpler without functional changes.
