* treewide: remove editor modelines and cruftMasahiro Yamada2021-05-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

* samples: configfs: drop unnecessary ternary operatorsBartosz Golaszewski2020-10-071-5/+5
| | | | | | | | | | | Checking pointers for NULL value before passing them to container_of() is pointless because even if we return NULL from the ternary operator, none of the users checks the returned value but they instead dereference it unconditionally. AFAICT this cannot really happen either. Simplify the code by removing the ternary operators from to_childless() et al.
