This patch do following optimizations to host controller reset: 1. Unblock scsi requests before rescanning topology, as SCSI command need be used if new device is found during rescanning topology. 2. Remove drain_workqueue(hisi_hba->wq) and drain_workqueue(shost->work_q), as there is no need to ensure that all PHYs event are done before exiting host reset. 3. Improve message print level of host reset. Host reset is an important and very few occurrence event. We should know its progress even when not debugging.

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.
