Junrui Luo 0c4a13ba88 ALSA: wavefront: Fix integer overflow in sample size validation 
The wavefront_send_sample() function has an integer overflow issue
when validating sample size. The header->size field is u32 but gets
cast to int for comparison with dev->freemem

Fix by using unsigned comparison to avoid integer overflow.

Takashi Iwai 4c267ae2ef ALSA: sb: Force to disable DMAs once when DMA mode is changed 
When the DMA mode is changed on the (still real!) SB AWE32 after
playing a stream and closing, the previous DMA setup was still
silently kept, and it can confuse the hardware, resulting in the
unexpected noises.  As a workaround, enforce the disablement of DMA
setups when the DMA setup is changed by the kcontrol.

Dr. David Alan Gilbert 174d966428 ALSA: msnd: Remove midi code 
Nothing calls snd_msndmidi_new()
  thus nothing sets chip->msndmidi_mpu
    The call to snd_msndmidi_input_read is gated on that being set,
    so snd_msndmidi_input_read() won't be called either.

This is probably a missing call to snd_msndmidi_new(), but since
this is ancient code, it's probably best to remove it (especially
since I don't have the hardware to test it).
