[PATCH v2 0/3] pinctrl: th1520: Improve code quality

[Drew Fustini <dfustini@xxxxxxxxxxxxxxx>]

This series contains code quality improvements for the new TH1520
pinctrl driver [1]:

 - Fix smatch warning that the return value is not correctly set when an
   unknown pin error occurs
 - Linus suggested using guarded mutexs so I've converted the thp->mutex
   lock to that usage.
 - Linus also suggested using a scoped iterator for the DT for-each
   child node loop: for_each_available_child_of_node_scoped.

The series is based on the linusw devel branch [2].

[2] https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git/log/?h=devel

Changes since v1:
- Move the scoped iterator conversion to a separate patch and remove the
  child put operations as they are no longer needed
- Link: https://lore.kernel.org/lkml/20241005-th1520-pinctrl-fixes-v1-0-5c65dffa0d00@xxxxxxxxxxxxxxx/
