I often do this aswell, apparently not all the time :-/

This message is also not seen often during booting since the driver has
this in it:

	/*
	 * The PMIC could already be initialized by the bootloader.
	 * Skip initialization here in this case.
	 */
	if (!pwrap_readl(wrp, PWRAP_INIT_DONE2)) {
		ret = pwrap_init(wrp);
		if (ret) {
			dev_dbg(wrp->dev, "init failed with %d\n", ret);
			goto err_out2;
		}
	}

I first have to comment out the already initialized check to see this
message. I just rechecked, yes, the initialisation still works as
expected.
