Why do you find the sentence for the multiplication information inappropriate
(or incomplete) at the moment?

Which details do you miss here?

Its implementation of the check “ALLOC_WITH_MULTIPLY” considers only an other
search pattern so far.

* Do you find it worthwhile to add a prefix like “devm_” to the used
  regular expression?

* Would like to improve any related scripts for the semantic patch language
  (Coccinelle software) a bit more?

Thanks for your feedback about other wording preferences.
