Subject: [PATCH V2] PCI: imx6: Do not output error message when devm_clk_get() failed with -EPROBE_DEFER
Date: Tue, 11 Aug 2020 09:29:24 +0800 [thread overview]
Message-ID: <1597109364-4739-1-git-send-email-Anson.Huang@nxp.com> (raw)
When devm_clk_get() returns -EPROBE_DEFER, i.MX6 PCI driver should
NOT print error message, use dev_err_probe() to handle it.
