[PATCH 6.1 0881/1146] mfd: pm8008: Fix return value check in pm8008_probe()

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

 



From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

[ Upstream commit 14f8c55d48e02157519fbcb3a5de557abd8a06e2 ]

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().
