From 12c2e32f14da857b58af281b029d4549d24c3292 Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: ethernet: bgmac: Fix return value check in bgmac_probe()
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().
