The patch fixes some checkpatch identified issues and adds a comment about
line discipline interaction to my driver code, as requested by Mark on my
inital submission (thank you Mark for applying my imperfect patch anyway).
It also fixes MODULE_ALIAS mismatch as used in my machine driver.

In my next attempt, I'll try to satisfy Mark's request for pushing down the
line discipline code, now existing in my machine driver, to the codec driver.
