This is a note to let you know that I've just added the patch titled locomo: make locomo_bus_type constant and static to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. From 2e9bf5cc912365d20e3255a0779f5516157b923e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Date: Tue, 19 Dec 2023 19:33:06 +0100 Subject: locomo: make locomo_bus_type constant and static MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that the driver core can properly handle constant struct bus_type, move the locomo_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime. It's also never used outside of arch/arm/common/locomo.c so make it static and don't export it as no one is using it.
