As Christoph Hellwig noted, SCSI commands that transfer data always have a SG entry. The patch removes dead code in mvumi_make_sgl(), mvumi_complete_cmd() and mvumi_timed_out() that handle zero scsi_sg_count(scmd) case. Also the patch adds pci_unmap_sg() on failure path in mvumi_make_sgl(). Signed-off-by: Alexey Khoroshilov <khoroshilov@ispras.ru> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.

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.
