Subject: [PATCH 4.18 020/235] ALSA: msnd: Fix the default sample sizes

4.18-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit 7c500f9ea139d0c9b80fdea5a9c911db3166ea54 ]

The default sample sizes set by msnd driver are bogus; it sets ALSA
PCM format, not the actual bit width.
