commit ca09b1bea63ab83f4cca3a2ae8bc4f597ec28851 upstream. On some devices (specifically the SC8180x based Surface Pro X with QCOM04A6) HC halt / xhci_halt() times out during boot. Manually binding the xhci-hcd driver at some point later does not exhibit this behavior. To work around this, double XHCI_MAX_HALT_USEC, which also resolves this issue.

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.
