Subject: [PATCH] mfd: pm8008: Fix return value check in pm8008_probe()
Git-commit: 14f8c55d48e02157519fbcb3a5de557abd8a06e2
Patch-mainline: v6.2-rc1
References: git-fixes
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().
