Yes, the "next" one, it's too late for 6.8-rc1, sorry. I'll look at it after -rc1 is out. thanks, greg k-h

The config HW_CONSOLE is always identical to the config VT and is not visible in the kernel's build menuconfig. So, CONFIG_HW_CONSOLE is redundant. Replace all references to CONFIG_HW_CONSOLE with CONFIG_VT and remove CONFIG_HW_CONSOLE. Signed-off-by: Lukas Bulwahn <lukas.bulwahn@gmail.com> --- I think this patch is best picked up by Greg rather than splitting it in smaller pieces for m68k, amiga keyboard, fbdev etc. Greg, if that is fine, could you pick this for the next merge window? I was also considering to rename config VT_HW_CONSOLE_BINDING to VT_CONSOLE_BINDING, as the dependency is on VT, not HW_CONSOLE, but at the moment, that seemed more churn than value of clarification. arch/m68k/amiga/config.c | 2 +- drivers/input/keyboard/amikbd.c | 6 +++--- drivers/tty/Kconfig | 7 +------ drivers/tty/vt/Makefile | 4 ++-- drivers/video/fbdev/tgafb.c | 2 +- include/linux/console.h | 2 +- lib/Kconfig.kgdb | 2 +- 7 files changed, 10 insertions(+), 15 deletions(-)
