commit8853b25030upstream. If the calls to platform_get_irq() or devm_request_irq() fail on probe of the SynQuacer SPI driver, the clock "sspi->clk" is erroneously not unprepared and disabled. If the clock rate "master->max_speed_hz" cannot be determined, the same happens and in addition the spi_master struct is not freed. Fix it.

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.
