Subject: [PATCH AUTOSEL 4.9 51/62] ALSA: riptide: Properly endian notations

From: Takashi Iwai <tiwai@...e.de>

[ Upstream commit be05e3de3a933156d472127f659d4473c461dcc5 ]

The SG descriptor of Riptide contains the little-endian values, hence
we need to define with __le32 properly.  This fixes sparse warnings
like:
  sound/pci/riptide/riptide.c:1112:40: warning: cast to restricted __le32
