Subject: [PATCH 5.14 038/849] ALSA: line6: fix control and interrupt message timeouts
From: Johan Hovold <johan@...nel.org>
commit f4000b58b64344871d7b27c05e73932f137cfef6 upstream.
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@...r.kernel.org # 2.6.30
