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 in v3:
 - Remove declaration of 'child' in th1520_pinctrl_dt_node_to_map() as
   the macro for_each_available_child_of_node_scoped already includes the
   declaration of 'child'.
 - Link to v2: https://lore.kernel.org/r/20241006-th1520-pinctrl-fixes-v2-0-b1822ae3a6d7@tenstorrent.com

Changes in v2:
 - Move the scoped iterator conversion to a separate patch and remove the
   child put operations as they are no longer needed
 - Link to v1: https://lore.kernel.org/lkml/20241005-th1520-pinctrl-fixes-v1-0-5c65dffa0d00@tenstorrent.com/
