I recommend to improve also this change description.
How do you think about a wording variant like the following?

   The function “devm_request_irq” is called after the
   function “platform_get_irq” in many drivers.
   The exception handling is incomplete there sometimes.
   Thus add a corresponding wrapper function for the simplification
   of the drivers.


Will a companion script for the semantic patch language (Coccinelle software)
become helpful for further support of collateral evolution?
