Aurelien Jarno aec2aef267 V4L/DVB (em28xx): Add support for Pinnacle Dazzle DVC 100 
The patch below adds the "Pinnacle Dazzle DVC 100" to the list of
cards supported by the em28xx driver. As the configuration is the same
as the DVC 90 one, it simply adds a new USB ID to the list of devices
supported by the DVC 90 configuration.
