Lukas Wunner 2737549129 spi: npcm-fiu: Don't leak SPI master in probe error path
commit 04a9cd51d3f3308a98cbc6adc07acb12fbade011 upstream.

If the calls to of_match_device(), of_alias_get_id(),
devm_ioremap_resource(), devm_regmap_init_mmio() or devm_clk_get()
fail on probe of the NPCM FIU SPI driver, the spi_controller struct is
erroneously not freed.

Fix by switching over to the new devm_spi_alloc_master() helper.

README

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.
