From c4db9934a33e5f276965a14b3eea7a6d64c85065 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 27 Apr 2020 09:40:52 +0000 Subject: [PATCH] net: ll_temac: Fix return value check in temac_probe() In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by: Wei Yongjun Acked-by: Esben Haabendal Signed-off-by: David S.
