error: initialization of ‘void (*)(struct usb_serial_port *)’ from incompatible pointer type ‘int (*)(struct usb_serial_port *)’

Hi I'm getting this error on ubuntu Ubuntu 22.04.1 LTS running the 5.15.0-53-generic kernel. Seems like something changed here?

sudo make
make -C /lib/modules/5.15.0-53-generic/build  M=/home/dominik/CH341SER_LINUX

Same here. Using Ubuntu 22.10. Exact same error while executing sudo make and sudo make load just gives a lot of errors afterwards.
