[PATCH 5.4 141/203] MIPS: Loongson: Fix return value of loongson_hwmon_init

[Greg Kroah-Hartman]

From: Tiezhu Yang <yangtiezhu@xxxxxxxxxxx>

commit dece3c2a320b0a6d891da6ff774ab763969b6860 upstream.

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