Merge v6.12-rc6 into usb-next
We need the USB fixes in here as well, and this resolves a merge conflict in: drivers/usb/typec/tcpm/tcpm.c Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Link: https://lore.kernel.org/r/20241101150730.090dc30f@canb.auug.org.au Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
