Subject: [PATCH] MIPS: Loongson: Fix return value of loongson_hwmon_init
commit dece3c2a320b0a6d891da6ff774ab763969b6860 upstream.
When call function hwmon_device_register failed, use the actual
return value instead of always -ENOMEM.
Fixes: 64f09aa967e1 ("MIPS: Loongson-3: Add CPU Hwmon platform driver")
