-Remove TTY_LDISC_MAGIC usage
-
-The 5.13 kernel removed the .magic field from tty_ldisc_ops and
-the associated TTY_LDISC_MAGIC #define, so remove their use when
-building for 5.13 or newer.

-Updates for 5.14
-
-The 5.14 kernel reworked the tty register and unregister call
-arguments, and made one of the arguments to the receive_buf
-callback const, add some kernel version conditionals to handle
-those.

-The fix to handle the backport of 4e096a18 to linux-5.4.y is a bit
