How do you think about a wording variant like the following?

   Subject:
   [PATCH v2] net: macb: Use devm_ioremap() in fu540_c000_init()

   Change description:
   A call of the macb_init() function can fail here.
   The corresponding system resources were not released then.
   Thus replace a call of the ioremap() function by devm_ioremap().
