Previous docs mentioned 11 unsigned long fields, when the reality is that
we have 15 fields with a mix of unsigned long and unsigned int.

Thank you very much, Greg! That was all for the tty tree.
I think that the other patches should go to the following trees:

The commit commit f991de53a8ab ("thermal: make device_register's type

This patch is partial from https://lkml.org/lkml/2019/5/14/631 which
