A call of the function macb_init() can fail in the function fu540_c000_init. The related system resources were not released then. use devm_platform_ioremap_resource() to replace ioremap() to fix it.

Thanks Nicolas! v1 -> v2: - Nicolas and Andy suggest use devm_platform_ioremap_resource() to repalce devm_ioremap() to fix this issue. Thanks Nicolas and Andy. - Yash help me to review this patch, Thanks Yash! drivers/net/ethernet/cadence/macb_main.c | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-)
