Subject: [PATCH -next] mfd: pm8008: Fix return value check in pm8008_probe()
Date: Thu, 3 Jun 2021 22:13:57 +0800 [thread overview]
Message-ID: <20210603141357.572347-1-yangyingliang@huawei.com> (raw)
In case of error, the function devm_regmap_init_i2c() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
Fixes: 6b149f3310a4 ("mfd: pm8008: Add driver for QCOM PM8008 PMIC")
Reported-by: Hulk Robot <hulkci@huawei.com>
