[PATCH 0/5] driver core: class: allow struct class to be static

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

There's been a semi-slow drip of driver core struct class changes
recently, and here's the final bit to the core that makes it possible
for 'struct class' to be moved into read-only memory.  And as proof, the
last patch in the series does just that for the tty classes.

After this series, there's some tree-wide cleanups needed to move away
from the class_create() api back to class_register() to move the
structures into read-only memory.  The class_create() api was a good
idea when it was created (as struct class was a dynamic structure), but
that got changed a long time ago and that's not necessary anymore.  But
that can wait for after 6.4-rc1 is out as they can all go through the
different relevant subsystems if wanted.

All of these apply on top of my latest driver-core.git driver-core-next
branch (or linux-next), as they require the current set of struct class
and struct bus_type reworks and have been tested locally (I'm typing
this and will send them out on a kernel running these changes).

Greg Kroah-Hartman (5):
  driver core: class: mark class_release() as taking a const *
  driver core: class: make class_register() take a const *
  driver core: class: mark the struct class in struct class_interface
    constant
  driver core: class: remove struct class_interface * from callbacks
  tty: make tty_class a static const structure
