Subject: [PATCH AUTOSEL 4.9 57/62] ALSA: au88x0: Fix sparse warning wrt PCM
 format type

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

[ Upstream commit 10d3d91e3bc4e152a580bf523e4fd6bf279ae532 ]

The PCM format type is with __bitwise, and it can't be converted from
integer implicitly.  Instead of an ugly cast, declare the function
argument of vortex_alsafmt_aspfmt() with the proper snd_pcm_format_t
type.

This fixes the sparse warning like:
  sound/pci/au88x0/au88x0_core.c:2778:14: warning: restricted snd_pcm_format_t degrades to integer
