5.4-stable review patch. If anyone has any objections, please let me know.

From: Christophe JAILLET christophe.jaillet@wanadoo.fr
[ Upstream commit 2b2bf6b7faa9010fae10dc7de76627a3fdb525b3 ]
'status' is known to be 0 at this point. The expected error code is PTR_ERR(clk).
Switch to dev_err_probe() in order to display the expected error code (in a human readable way). This also filters -EPROBE_DEFER cases, should it happen.
