Subject: [PATCH v4] pwm: rockchip: Convert to use dev_err_probe()
Date: Fri, 19 Aug 2022 17:26:27 +0800	[thread overview]
Message-ID: <20220819092627.19416-1-zhaoxiao@uniontech.com> (raw)

It's fine to call dev_err_probe() in ->probe() when error code is known.
Convert the driver to use dev_err_probe().

 v4: add the missing dev_err function.
