[Line6linux-devel] [PATCH 0/5] staging: line6: more fixes and cleanups

[<ste...@gm...>]

From: Stefan Hajnoczi <ste...@gm...>

I have been testing PulseAudio, ALSA, and jack applications with a POD HD300
because they tend to produce different call patterns.  This is useful for
exposing bugs.  This series includes the latest fixes as well as some code
cleanups.

The fixes I'd like to highlight are:

Patch 1 resolves a potential memory leak which I introduced when moving buffer
allocation into the .hw_params() pcm callback.

Patch 3 ensures that the playback buffer is used correctly irrespective of urb
completion order.  I'm not certain what guarantees we have on iso urb
completion order so this may not be a real problem but it at least simplifies
the code.

Patch 5 makes jackd work by eliminating the -EBUSY error when it tries to start
a stream.

Stefan Hajnoczi (5):
  staging: line6: fix memory leak in .hw_params()
  staging: line6: fix playback urb transfer buffer calculation
  staging: line6: eliminate useless index_out variable
  staging: line6: eliminate useless NULL checks
  staging: line6: wait for urbs in snd_line6_prepare()
