I am trying another software analysis approach out for the presentation
of null pointer usage.

Jia-Ju Bai contributed patches based on analysis results from
the tool “STCheck” by the OSLAB group of the Tsinghua University.
Some corresponding improvements are in the review queue.

A specific script is available also for the semantic patch language.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/coccinelle/null/deref_null.cocci?id=a55aa89aab90fae7c815b0551b07be37db359d76

Can this SmPL script become able to point remaining update candidates out
in similar ways?

Examples for further considerations:
* fs: xfs: Fix possible null-pointer dereferences in 
xchk_da_btree_block_check_sibling()
