Staging: sst: fixups in SNDRV_SST_STREAM_DECODE
This is another patch about copying data to the kernel before using it.
SNDRV_SST_STREAM_DECODE is sort of tricky because we need to do a
copy_from_user() that gives us another two pointers and we have copy
those. Those again give us some more pointers that we have to copy.
Besides those problems, the code had a stack overflow:
- struct snd_sst_buff_entry ibuf_temp[param->ibufs->entries],
- obuf_temp[param->obufs->entries];
param->ibufs->entries comes from the user.
