From 45432d41a2eebf5daaacb81de37fbfffc0a8faa7 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 7 May 2012 06:53:27 -0300 Subject: [PATCH] [media] gspca_gl860: Add a present check to sd_stop0 The sensor specific dev_post_unset_alt functions all try to write to the bridge, and none free any memory, so they should be skipped if stop0 is called on disconnection.
