Generate modules.builtin.alias from match ids This patch series (v10) generates `modules.builtin.alias` during modpost. The goal is for tools like USBGuard to leverage not only modules.aliases but also `modules.builtin.aliases` to associate devices with the modules that may be bound before deciding to authorize a device or not. This is particularly useful in cases when new devices of a particular type shouldn't be allowed part of the time like for lock screens. Also included in this series are added documentation, style fixes and fixes for build breakages for built-in modules that relied on MODULE_DEVICE_TABLE being a no-op. Some of these were typos in device table name that do not need aliases and one ifdef-ed out the device table. --- Generate modules.builtin.alias from match ids ============================================= This series (v10) removes the `cc:stable` commit tags since the fixes only are needed going forward. It also includes documentation updates and unifies the MODULE_DEVICE_TABLE macro for both the builtin and module case. Additionally, rather than fixing the typo-ed device table names the commits were updated to drop the broken MODULE_DEVICE_TABLE invocations, since they belong to device types that would not benefit from the intended purpose of `modules.builtin.alias`. Note, cover letters were first added in v5.

Acknowledgements ---------------- Thanks to Greg Kroah-Hartman, Christophe Leroy, Luis Chamberlain and the other Linux maintainers for being patient with me as I have worked through learning the kernel workflow to get this series into a more presentable state. Thanks to Luis Chamberlain for raising the alternative of using kmod to address the primary motivation of the patch series. Thanks to Dmitry Torokhov and Benson Leung for feedback on the USB authorization documentation for the driver API. Also, thanks to Intel's kernel test robot <lkp@intel.com> for catching issues that showed up with different kernel configurations.
