Subject: [PATCH -next resend 1/5] usb: musb: core: Switch to use dev_err_probe() helper
Date: Mon, 26 Sep 2022 22:15:06 +0800	[thread overview]
Message-ID: <20220926141510.2265523-2-yangyingliang@huawei.com> (raw)
In-Reply-To: <20220926141510.2265523-1-yangyingliang@huawei.com>

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.
