upf_t is a bitwise defined type and any assignment from different, but compatible, types makes static analyzer unhappy. drivers/tty/serial/serial_core.c:793:29: warning: incorrect type in assignment (different base types) drivers/tty/serial/serial_core.c:793:29: expected int [signed] flags drivers/tty/serial/serial_core.c:793:29: got restricted upf_t [usertype] flags drivers/tty/serial/serial_core.c:867:19: warning: incorrect type in assignment (different base types) drivers/tty/serial/serial_core.c:867:19: expected restricted upf_t [usertype] new_flags drivers/tty/serial/serial_core.c:867:19: got int [signed] flags Enforce corresponding types when upf_t being assigned.
