I find that the corresponding documentation of these programming interfaces is incomplete for a desired format which could be different than C source code. https://elixir.free-electrons.com/linux/v4.15-rc1/source/include/linux/device.h#L657 https://elixir.free-electrons.com/linux/v4.15-rc1/source/drivers/base/devres.c#L763 https://www.kernel.org/doc/html/latest/driver-api/basics.html#c.devm_kmalloc Can the Coccinelle software help more to determine desired function properties? >> For which hardware and software combinations would you like to see >> facts there? > > This is not for Joe to decide, This view is fine in principle. > it's for the person who receives the patch to decide.

The variation space could become too big to handle for me (alone). How will this aspect evolve further?
