[vlc-devel] [PATCH] Enforce null pointer replacement on msg_Foo debug strings

Of course, as I mentioned all replacements are not required:

find . -name "*.c*" -exec grep -E "msg_(Dbg|Err|Warn)" {} \; | wc -l
6603

gives you an idea why I didn't spent my time backtracking every string 
variable used in debug strings. Restricting analysis to the editor's viewport 
already took too much time.

Yes, if you have a particular library code in mind(*), please patch the same 
way you already did for vasprintf.

* note it needs the special '%m' format in some places
