Yes, this patch fixes this particular problem.
There is just a typo in the code which causes a build problem but it's fixed by
replacing
"uport" with "port":
CC kernel/module.o
drivers/tty/serial/serial_core.c: In function ‘uart_configure_port’:
drivers/tty/serial/serial_core.c:2385:33: error: ‘uport’ undeclared (first use
in this function); did you mean ‘port’?
2385 | uart_any_port_spin_lock_init(uport);
| ^~~~~
| port
drivers/tty/serial/serial_core.c:2385:33: note: each undeclared identifier is
reported only once for each function it appears in
make[3]: *** [scripts/Makefile.build:280: drivers/tty/serial/serial_core.o]
Error 1
make[2]: *** [scripts/Makefile.build:497: drivers/tty/serial] Error 2
make[1]: *** [scripts/Makefile.build:497: drivers/tty] Error 2

Will test the other changes in a minute.
Can we include the serial fix?
