From 90211b58828924577b589e59814f53aec4557fb9 Mon Sep 17 00:00:00 2001 From: Xingyu Wu Date: Wed, 26 Apr 2023 11:12:16 +0800 Subject: [PATCH] watchdog: starfive: Fix the probe return error if PM and early_enable are both disabled When the starfive watchdog driver uses 'pm_runtime_put_sync()' as probe return value at last and 'early_enable' is disabled, it could return the error '-ENOSYS' if the CONFIG_PM is disabled, but the driver should works normally. Drop the 'return' and keep the 'pm_runtime_put_sync()', but do not use it as the return value.
