sparc64:allmodconfig:

In file included from drivers/tty/serial/serial_mctrl_gpio.c:21:0:
include/uapi/asm-generic/termios.h:22:8: error: redefinition of 'struct termio'
./arch/sparc/include/uapi/asm/termbits.h:16:8: note: originally defined here
make[3]: *** [drivers/tty/serial/serial_mctrl_gpio.o] Error 1

Caused by commit 62b0a1b3e759 ('serial: clps711x: Use mctrl_gpio helpers for
handling modem signals'), which enables SERIAL_MCTRL_GPIO for this build,
but SERIAL_MCTRL_GPIO doesn't work for sparc64.
