commit61f7a8f975upstream. The previous fix was incomplete as the link failure still persists with CONFIG_USB=m when the sdio or serial wrappers for btmtk.c are build-in: btmtk.c:(.text+0x468): undefined reference to `usb_alloc_urb' btmtk.c:(.text+0x488): undefined reference to `usb_free_urb' btmtk.c:(.text+0x500): undefined reference to `usb_anchor_urb' btmtk.c:(.text+0x50a): undefined reference to `usb_submit_urb' btmtk.c:(.text+0x92c): undefined reference to `usb_control_msg' btmtk.c:(.text+0xa92): undefined reference to `usb_unanchor_urb' btmtk.c:(.text+0x11e4): undefined reference to `usb_set_interface' btmtk.c:(.text+0x120a): undefined reference to `usb_kill_anchored_urbs' Disallow this configuration.

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.
