    Subject[PATCH 4.19 622/639] MIPS: Loongson: Fix return value of loongson_hwmon_init
    Date
    From: Tiezhu Yang <yangtiezhu@loongson.cn>

    [ Upstream commit dece3c2a320b0a6d891da6ff774ab763969b6860 ]

    When call function hwmon_device_register failed, use the actual
    return value instead of always -ENOMEM.
