Landed in mainline as 593135f09368 on 2023-08-04.
Fixes following sparse warning:
drivers/tty/serial/8250/8250_men_mcb.c:92:21: sparse: cast removes
address space '__iomem' of expression
drivers/tty/serial/8250/8250_men_mcb.c:92:21: sparse: incorrect type
in argument 1 (different address spaces) expected void const volatile
[noderef] __iomem *addr got void *
