I recommend to improve also this change description. How do you think about a wording variant like the following? The function =E2=80=9Cdevm_request_irq=E2=80=9D is called after the function =E2=80=9Cplatform_get_irq=E2=80=9D 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 softwa= re) become helpful for further support of collateral evolution? Regards, Markus
