This is also a clean-up patch while patch 2 is a driver update so I would
provide this patch (currently patch 3) before the patch updating to use guard().

I'd break the lines and write the message in the line below for this and other
dev_err_probe() that exceed 80 columns. E.g.

		return dev_err_probe(&spi->dev, ret,
				     "failed to enable AVDD supply\n");

Note this is just a personal preference of mine, not enforced code style, so
fine if you prefer keep it as it is.
