Subject: [PATCH] mISDN: remove unneeded mISDN_class_release()

From: Greg Kroah-Hartman <[email-masked]>
Date: Wed, 29 Mar 2023 08:01:27 +0200

The mISDN_class_release() is not needed at all, as the class structure
is static, and it does not actually do anything either, so it is safe to
remove as struct class does not require a release callback.

Note: I would like to take this through the driver-core tree as I have
later struct class cleanups that depend on this change being made to the
tree if that's ok with the maintainer of this file.
