[PATCH] ethernet/stmicro: Use devm_platform_ioremap_resource_byname

From: dingsenjie
Date: Fri Apr 30 2021 - 01:53:00 EST


From: dingsenjie <dingsenjie@xxxxxxxxxx>

Use the devm_platform_ioremap_resource_byname() helper instead of
calling platform_get_resource_byname() and devm_ioremap_resource()
separately.
