[PATCH -next 2/2] drm/arm/hdlcd: Use devm_platform_ioremap_resource()

[PATCH -next 2/2] drm/arm/hdlcd: Use devm_platform_ioremap_resource()

[Yang Li]

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'.

Thanks for the cleanup! I will pull this patch and the hdlcd one into
drm-misc-next by the end of the week.

Best regards,
