This removes regulator_lock/unlock() calls around regulator_notifier_call_chain() as they are redundant - drivers already have to guarantee regulator_dev's existence during the call. This should make reasoing about the lock easier, as this was the only use outside regulator core code. The only client that needed recursive locking from the notifier chain was drivers/usb/host/ohci-da8xx.c, which responds to over-current notification by calling regulator_disable().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
