ata_sff_qc_issue() expects upper layers to never issue commands on a command protocol that it doesn't implement. While the assumption holds fine with the usual IO path, nothing filters based on the command protocol in the passthrough path (which was added later), allowing the warning to be tripped with a passthrough command with the right (well, wrong) protocol. Failing with AC_ERR_SYSTEM is the right thing to do anyway. Remove the unnecessary WARN.

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.
