[alsa-devel] [PATCH 03/14] ALSA: hda: Proper endian notations for BDL pointers

[Takashi Iwai]

The BDL pointer used in snd_hdac_dsp_prepare() should be declared as
__le32, as warned by sparse:
  sound/hda/hdac_stream.c:655:47: warning: incorrect type in argument 4 (different base types)
  sound/hda/hdac_stream.c:655:47:    expected restricted __le32 [usertype] **bdlp
  sound/hda/hdac_stream.c:655:47:    got unsigned int [usertype] **<noident>
