The warn on is a bit too much, we will anyway set the dma mask if not set previously. The main reason for this fix is that 4.10-rc1 has a dwc3 change that pass a parent sysdev dev pointer instead of setting the dma mask of its xhci platform device. xhci platform driver can then get more attributes from the sysdev than just the dma mask. The usb core and xhci changes are not yet in 4.10, and a fix like this was preferred instead of taking those big changes this late in the rc-cycle.

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.
