devres: Improve devm_kasprintf()/kvasprintf() support
- Add devm_kasprintf()/kvasprintf(), introduced by commit
75f2a4ead5d5890ada9c2663a70fb58613c0d9f2 ("devres: Add
devm_kasprintf and devm_kvasprintf API"), to
Documentation/driver-model/devres.txt,
- Improve kernel doc: the string is not an existing formatted string,
but is formatted into the newly-allocated buffer,
- Add a __printf() annotation to devm_kasprintf(), so the compiler
will verify the format string argument types.
