[PATCH AUTOSEL 4.14 78/89] ALSA: pcm: Fix sparse warning wrt PCM format type

From: Takashi Iwai <tiwai@xxxxxxx>

[ Upstream commit f8b6c0cfbdd7359db9bb4da38dd54217296f9264 ]

The PCM format type is with __bitwise, hence it needs the explicit
cast with __force. It's ugly, but there is a reason for that cost...

This fixes the sparse warning:
sound/core/oss/pcm_oss.c:1854:55: warning: incorrect type in argument 1 (different base types)
