Subject: [PATCH 4.9 021/157] media: s2255: fix control-message timeouts

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

commit f71d272ad4e354097020a4e6b1dc6e4b59feb50f upstream.

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

Use the common control-message timeout define for the five-second
timeouts.

Fixes: 38f993ad8b1f ("V4L/DVB (8125): This driver adds support for the Sensoray 2255 devices.")
