Remove redundant else blocks following return or break
statements.As control flow exits in these cases, the
else branch is unnecessary.Dropping it improves code
readability.

There is a room for more words on the lines. Also respect English grammar and
punctuation, exempli gratia use space after a punctuation.

Now it may occupy two lines only.

	dev_err(isp->dev, "%s: error in iunit interrupt. status reg=0x%x\n",
		__func__, irq);
