commit58ac1b3799upstream. Since there is no guarantee that the memory returned by dma_alloc_coherent() is associated with a 'struct page', using the architecture specific phys_to_page() is wrong, but using virt_to_page() would be as well. Stop using sg lists altogether and just use the *_single() functions instead. This also simplifies the code a bit since the scatterlists in this driver always have only one entry anyway. https://lore.kernel.org/lkml/86db0fe5-930d-4cbb-bd7d-03367da38951@app.fastmail.com/ Use consistent names for dma buffers gc: Add a commit log from the initial thread: https://lore.kernel.org/lkml/86db0fe5-930d-4cbb-bd7d-03367da38951@app.fastmail.com/ Use consistent names for dma buffers Fixes:cb06ff102e("ARM: PL011: Add support for Rx DMA buffer polling.")

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.
