      [media] gspca-ov534: don't call sd_start() from sd_init() · d48de1c7
      由 Antonio Ospite 提交于 
      sd_start() operates on device controls but after the conversion to the
v4l2 control framework in commits 62bba5dd and 1bd7d6ad controls are
initialized in sd_init_controls() which is called _after_ sd_init():
The change fixes a NULL pointer dereference for Hercules Blog Webcam;
the problem is observable since 3.6:

      USB: convert drivers/media/* to use module_usb_driver() · ecb3b2b3
      由 Greg Kroah-Hartman 提交于 
      This converts the drivers in drivers/media/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.
