After initiating a sideband transaction, we only want to wait for the transaction to become idle. If, as we are, we wait for both the busy and error flag to clear, if an error is raised we just spin until the timeout. Once the hw is idle, we can then check to see if the hw flagged an error, and report it distinctly.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
