From fcd62cf7f62a67976b72669934127cb4ecee2b1e Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Wed, 1 Apr 2009 01:55:26 -0300 Subject: V4L/DVB (11334): pvrusb2: Fix uninitialized tuner_setup field(s) Any time a struct (especially one not defined by this driver) is allocated, we MUST zero its underlying storage. This makes our usage of the struct predictable and robust against future changes where fields might be added that we don't know about. Failing to do this with tuner_setup left the config field uninitialized which then caused trouble with the tuner type used for HVR-1950 devices.
