[Why] The new aux implementation was not up to spec. This caused us to fail DP compliance as well as introduced serious delays during system resume. [How] Make dce_aux_transfer_raw return the operation result Make dce_aux_transfer_with_retries delay with udelay instead of msleep, and only on invalid reply. Also fail on the second invalid reply, third timeout, or first of any other error Convert return values to drm error codes in amdgpu_dm As the two aux transfer functions are now noticeably different, change the names to better reflect their functionality and document.

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.
