From 2ca8c763ae0cb517de6058cb9142877c96220a03 Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Mon, 4 Nov 2019 21:33:50 +0800 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.
