Yang Yingliang e82c6d62a1 spi: microchip-core: fix UAF in mchp_corespi_remove()
When using devm_spi_register_master(), the unregister function will
be called in devres_release_all() which is called after ->remove(),
so remove spi_unregister_master() andspi_master_put().

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.
