From: Yang Guang <yang.guang5@xxxxxxxxxx>
dev_err_probe() can check if the error code is -EPROBE_DEFER
and can return the error code, replacing dev_err() with it
simplifies the code.

Got the following checkpatch error:
ERROR:NO_AUTHOR_SIGN_OFF: Missing Signed-off-by: line by nominal patch author 'Yang Guang <yang.guang5@xxxxxxxxxx>'
Thanks,
