Subject: [PATCH -next] phy: sparx5_serdes: Fix return value check in sparx5_serdes_probe()
Date: Thu, 18 Mar 2021 13:56:47 +0000 [thread overview]
Message-ID: <20210318135647.1286295-1-weiyongjun1@huawei.com> (raw)
From: Wei Yongjun <weiyongjun1@huawei.com>
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.
Fixes: 2ff8a1eeb5aa ("phy: Add Sparx5 ethernet serdes PHY driver")
Reported-by: Hulk Robot <hulkci@huawei.com>
Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com>
