[PATCH net-next v3] mfd: pm8008: Fix return value check in pm8008_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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")
