Second stage of HDCP authentication starts at CP_IRQ or at the assertion of READY bit from Repeater. Till then repeater will be authenticating with its downstream devices. So authenticated device count, depth and ksv_list readable from repeaters are valid only after assertion of READY/CP_IRQ. This patch makes sure that READY is polled before reading any topology information.

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.
