Subject: [PATCH 4.14 013/251] ALSA: 6fire: fix control and bulk message timeouts

From: Johan Hovold <johan@...nel.org>

commit 9b371c6cc37f954360989eec41c2ddc5a6b83917 upstream.

USB control and bulk message timeouts are specified in milliseconds and
should specifically not vary with CONFIG_HZ.

Fixes: c6d43ba816d1 ("ALSA: usb/6fire - Driver for TerraTec DMX 6Fire USB")
