[greybus-dev] Re: [PATCH] staging: greybus: codecs: fix type confusion with dedicated list iterator variable

The subject says that it fixes a bug but it does not.

If the list does not exit early then data == NULL and 'module' does not point to a valid list element. Using 'module' in such a case is not valid and was therefore removed.

This paragraph is confusing jumble words. Just say: "This code is fine".

In preparation to limit the scope of the list iterator to the list traversal loop, use a dedicated pointer pointing to the found element [1].

This paragraph is the information we need. Just add something like "This patch has no effect on runtime".
