The pl330 driver re-uses DMA descriptors rather than reallocating them each time. At present, upon re-use the .callback member is cleared, but .callback result is not. This causes problems where a consuming driver sets the .callback_result for some submissions but not for others, as eventually the function is invoked erronously. Clear .callback_result along with .callback Signed-off-by: Daniel Scally <dan.scally@ideasonboard.com> Link: https://lore.kernel.org/r/20240118112959.1027471-1-dan.scally@ideasonboard.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
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.
