Merge tag 'sh-for-v6.9-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
"Two patches by Ricardo B. Marliere make two instances of struct
bus_type in the interrupt controller driver and the DMA sysfs
interface const since the driver core in the kernel is now able to
handle that.

A third patch by Artur Rojek enforces internal linkage for the
function setup_hd64461() in order to fix the build of hp6xx_defconfig
with -Werror=missing-prototypes"
