Pull spi fixes from Mark Brown: "A small set of fixes here. One core fix for error handling when we fail to set up the hardware before initiating a transfer and another one reverting a change in the core which broke Raspberry Pi in common use cases as part of some optimization work. There's also a couple of driver specific fixes" * tag 'spi-fix-v5.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: abort spi_sync if failed to prepare_transfer_hardware spi: spi-fsl-spi: call spi_finalize_current_message() at the end spi: bitbang: Fix NULL pointer dereference in spi_unregister_master spi: Fix Raspberry Pi breakage
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.
