NACK. The before and after of this patch are functionally identical. The if-block returns unconditionally ("return priv;"), so the kfree will only ever be reached if the condition in the if-statement evaluates to false. Explicitly writing out an else-block is thus superfluous.

Hi, I think there has a incorrect kfree in pcirom_init function. In
pcirom_init function priv porinter could be free only when priv != null
and priv->rom is null.
