[PATCH 2/2] sound: line6: fix control and interrupt message timeouts

From: Johan Hovold <johan@kernel.org>
Date: 2021-10-25 12:12:34
Also in: alsa-devel, lkml, stable
Subsystem: sound, the rest · Maintainers: Jaroslav Kysela, Takashi Iwai, Linus Torvalds 

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

Fixes: 705ececd1c60 ("Staging: add line6 usb driver")
Cc: stable@vger.kernel.org      # 2.6.30
Signed-off-by: Johan Hovold <johan@kernel.org>
