[ Upstream commit7a2148dfda] The current code decrements the timeout counter i and the end of each loop i is incremented, so the check for timeout will always be false and hence the timeout mechanism is just a dead code path. Potentially, if the RD_READY bit is not set, we could end up in an infinite loop. Fix this so the timeout starts from 1000 and decrements to zero, if at the end of the loop i is zero we have a timeout condition.

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.
