drm/mediatek: Use devm_platform_get_and_ioremap_resource() in mtk_hdmi_ddc_probe()

elfring · Chun-Kuang Hu · commit d64e9d0fb618 · 2024-04-01T14:02:19.000Z
A wrapper function is available since the commit 890cc39 ("drivers: provide devm_platform_get_and_ioremap_resource()"). Thus reuse existing functionality instead of keeping duplicate source code. This issue was detected by using the Coccinelle software.
