2012-07-30[media] gspca: Add reset_resume callback to all sub-driversHans de Goede
1) The gspca-core's suspend/resume code is such that resume being called after a reset is safe / ok. 2) All devices tested sofar seem to need the reset_resume callback to work properly over a suspend 3) The USB-core won't call the reset_resume callback for devices which don't need it Thus it seems the simplest and the best to just add the callback to all sub-drivers, rather then adding the callbacks one-by-one as each driver gets tested with suspend/resume.

2012-07-30[media] gspca: Remove bogus JPEG quality controls from various sub-driversHans de Goede
Various gspca-subdrivers have a JPEG quality control which only changes the quantization tables in the JPEG headers send to user-space without making any changes to the settings of the bridge. Remove these bogus / wrong controls. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-11-18USB: convert drivers/media/* to use module_usb_driver()Greg Kroah-Hartman
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.
