Subject[PATCH 5.10 186/717] staging: mfd: hi6421-spmi-pmic: fix error return code in hi6421_spmi_pmic_probe()
Date
From: Wang Hai <wanghai38@huawei.com>

[ Upstream commit ba3e4a2a0b3c639d3835f2f1dce27d79576ae453 ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 4524ac56cdca ("staging: mfd: add a PMIC driver for HiSilicon 6421 SPMI version")
