[PATCH] watchdog: ar7_wdt: Make use of the helper function devm_platform_ioremap_resource_byname()

From: Cai Huoqing
Date: Tue Sep 07 2021 - 03:43:21 EST


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