Subject: [PATCH AUTOSEL 4.14 79/89] ALSA: wss: Fix sparse warning wrt PCM
 format type

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

[ Upstream commit 6be9a60efb401487a4d658ef23d652a9e6860b34 ]

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 snd_wss_get_format() with the proper snd_pcm_format_t
type.

This fixes the sparse warnings like:
  sound/isa/wss/wss_lib.c:551:14: warning: restricted snd_pcm_format_t degrades to integer
