malloc/calloc return value NULL check

[Baesken, Matthias]

Hi, when playing around with the  GCC static analyzer  ( https://developers.redhat.com/articles/2022/04/12/state-static-analysis-gcc-12-compiler )   I noticed
a lot of complaints about  missing  NULL checks of  malloc/calloc  return values in the code base.

While we check these return values for NULL at a lot of places in the codebase,  it is not done always.
Should we do it always  (except 3rd party code probably where we do not want to have large diffs to upstream) ?

Or is it considered not important enough  to do it always?

Best regards, Matthias
