Generate modules.builtin.alias from match ids This patch series (v8) 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 the device table name and one ifdef-ed out the device table. -- # Generate modules.builtin.alias from match ids This series (v8) adds missing `cc:stable` and `fixes:` commit tags to the relevant commits. It is unlikely these drivers were being built as modules because compilation would have failed. It also updates the build documentation to cover `modules.builtin.alias`. Note, cover letters were first added in v5.

I believe there is potential to improve the Makefile part of the patch series as well as an open question of whether modpost should generate `modules.built.alias` directly or create a vmlinuz.mod.c containing the missing module info for the match-id based aliases for built-in modules. ## 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. Also, thanks to Intel's kernel test robot <lkp@xxxxxxxxx> for catching issues that showed up on different kernel configurations.
