net/mlxbf_gige: Make use of devm_platform_ioremap_resourcexxx()
Use the devm_platform_ioremap_resource_byname() helper instead of calling platform_get_resource_byname() and devm_ioremap_resource() separately Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing <caihuoqing@baidu.com> Signed-off-by: David S.
