From 1808a698a87366f9d82945270355c2139df0a16d Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 29 Oct 2007 17:38:59 -0300 Subject: [PATCH] V4L/DVB (6475): Fix some troubles at list handling - priv->count were wrong. Should be incremented since the first usage; - forgot to use list_del() to remove the driver; - Release memory if an error occurs during _attach Thanks to Aidan Thornton for pointing this.
