It's really annoying to see that in 2020 we're still facing bugs caused
by dangling pointers in the code that result from poorly written rules
about how these pointers are supposed to be handled, set and reset. Let's
add a few supposedly obvious (but apparently not) rules about how pointers
have to be used through out the code in hope to make such bad practices
disappear (or at least have something to point the authors to after
reviewing their code).

Running the Linux kernel's checkpatch.pl is actually quite efficient
at spotting style issues and even sometimes bugs. The doc now suggests
how to use it to avoid the warnings that are specific to Linux's stricter
rules.
It properly reports errors like the following ones that were found on
real submissions so it should improve the situation for everyone :
ERROR: "foo * bar" should be "foo *bar"
+static char * tcpcheck_get_step_comment(struct check *, int);
ERROR: do not use assignment in if condition
+ if ((comment = tcpcheck_get_step_comment(check, step)))
