The documentation is pretty good actually and it belongs where it
is. But 35 characters is just tooooooooooooooooooooooooooooooooooo
long.
To me the word "INDEX_" is confusing because what are we indexing?
In this context it means the the variable is a bit flag. That was
obvious because we were calling test_bit().
I think we could drop the PCM_ as well, because why do we need that?
We could change the LINE6 to L6.
if (test_bit(L6_ALSA_CAPTURE_STREAM, &line6pcm - flags)
It fits!
