From 98522a7be97f2b23451342e36c39f412f0461e24 Mon Sep 17 00:00:00 2001 From: Jean-Francois Moine Date: Tue, 18 Nov 2008 06:33:08 -0300 Subject: V4L/DVB (9689): gspca: Memory leak when disconnect while streaming. As a side effect, the sd routine stop0 is called on disconnect. This permits the subdriver to free its resources.
