This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs. The simplest fix, explained in detail in Lukas' commit message, is to move to a devm_ function for allocation of the controller and hence driver data in order to push the free of that after anything tries to reference the driver data in the remove path. This results in a relatively large diff due to the addition of a new function but isn't particularly complex. There's also a fix from sven van Asbroeck which fixes yet more fallout from the conflicts between the various different places one can configure the polarity of GPIOs in modern systems. Otherwise everything is fairly small and driver specific. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl+2qqsACgkQJNaLcl1U h9DN/gf+P85QtRuWq8hGt9cEywwvPXdYEifxlJuevO+RIzyrI7y6hc2AqmQ/ek2Q kRU39CVLzrm+P8GRX/K6wL8sSQmBVJSt25aWwYKiygidh4eFqmDKC5y/yQY+VIoW /MvFpdFOENDbAjRRK3l5x9BdwXsNPadjl7Ts2FGyjsBOOEWdXf9fApXju7oVHGki oDc35Z5o1DdwTdTD5B/uKP2VmevbrEmBceGZttaSUjyO4kJ9ehe+kJ1DuBu9QrTN GDu/J7oijbtYYfRi6DeMjVfUvvNK9c+6TQay91j0c6ZNW5TuYkZ0XS1vbpjwshQg wWPxA+uQ4YelNgRQ4H+PhzOKo0zv4A== =oG9R -----END PGP SIGNATURE----- Merge tag 'spi-fix-v5.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs.

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.
