drivers/char/tty_buffer.c: In function ‘tty_insert_flip_string_fixed_flag’:
drivers/char/tty_buffer.c:251: warning: comparison of distinct pointer types lacks a cast
drivers/char/tty_buffer.c: In function ‘tty_insert_flip_string_flags’:
drivers/char/tty_buffer.c:288: warning: comparison of distinct pointer types lacks a cast

Fix it by replacing min() with min_t() in tty_insert_flip_string_flags and
  tty_insert_flip_string_fixed_flag().
