This is a note to let you know that I've just added the patch titled PNP: Hide pnp_bus_type from the non-PNP code to the 6.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: pnp-hide-pnp_bus_type-from-the-non-pnp-code.patch and it can be found in the queue-6.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 3b324fcdc6d517efa322c94f6c87407a6acc303d Author: Andy Shevchenko <andy.shevchenko@xxxxxxxxx> Date: Tue May 28 13:25:03 2024 +0300 PNP: Hide pnp_bus_type from the non-PNP code [ Upstream commit edcde848c01eb071a91d479a6b3101d9cf48e905 ] The pnp_bus_type is defined only when CONFIG_PNP=y, while being not guarded by ifdeffery in the header. Moreover, it's not used outside of the PNP code. Move it to the internal header to make sure no-one will try to (ab)use it.
