[ Upstream commit aa5dc05340eb97486a631ce6bccb8d020bf6b56b ] [Why] Fix minor issues in BW Allocation Phase2. [How] - In set_usb4_req_bw_req(), link->dpia_bw_alloc_config.response_ready flag should be reset before writing DPCD REQUEST_BW. - Fix the granularity for value of 2 in get_bw_granularity(). - Removed bandwidth allocation support display fw boot option as the fw would read feature enable status from bios. - Clean up DPIA_EST_BW_CHANGED and DPIA_BW_REQ_SUCCESS cases in dpia_handle_bw_alloc_response(). - Removed allocate_usb4_bw and deallocate_usb4_bw. - Optimized loop in get_lowest_dpia_index(). - Updated link_dp_dpia_allocate_usb4_bandwidth_for_stream() and set_usb4_req_bw_req() to always issue request bw.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
