Commit702b15cb97("spi: mt7621: fix missing clk_disable_unprepare() on error in mt7621_spi_probe") sought to disable the SYS clock on probe errors, but only did so for 2 of 3 potentially failing calls: The clock needs to be disabled on failure of devm_spi_register_controller() as well. Moreover, the commit purports to fix a bug in commitcbd66c626e("spi: mt7621: Move SPI driver out of staging") but in reality the bug has existed since the driver was first introduced.

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.
