The rkisp1_register_capture() and rkisp1_unregister_capture() functions don't destroy the mutex (in the error path for the former). Fix this and make rkisp1_unregister_capture() and rkisp1_capture_devs_unregister() safe to be called on an unregistered capture node to prepare for simplification of error handling at probe time. While at it, drop the double initialization of cap->rkisp1 in rkisp1_capture_devs_register() as the field is already initialized in rkisp1_capture_init().

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.
