John Cox 60e9069014 arm64/dma-mapping: Fix arch_sync_dma_for_device to respect dir parameter
All other architectures do different cache operations depending on the
dir parameter. Fix arm64 to do the same.

This fixes udmabuf operations when syncing for read e.g. when the CPU
reads back a V4L2 decoded frame buffer.

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.
