commit 8f18973877204dc8ca4ce1004a5d28683b9a7086 upstream.
The code "lchan = (lchan << 1) | ~lchan" for logical channel
intermediate decoding is wrong. The wrong intermediate decoding
result is {0xffffffff, 0xfffffffe}.
Fix it by replacing '~' with '!'. The correct intermediate
decoding result is {0x1, 0x2}.

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.
