2008-11-24V4L/DVB (9691): gspca: Move the video device to a separate area.Jean-Francois Moine
The video device was part of the gspca device. On device disconnection while streaming, the device structure is freed at close time. In this case, the remaining close job on the video device run out of allocated memory. Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-11-24V4L/DVB (9690): gspca: Lock the subdrivers via module_get/put.Jean-Francois Moine
The previous subdriver protection against rmmod was done via the file operations table in the device descriptor. On device disconnection while streaming, the device structure was freed at close time, and the module_put still used the module name in the freed area. Now, explicit module get/put are done on open and close. Signed-off-by: Jean-Francois Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-11-24V4L/DVB (9689): gspca: Memory leak when disconnect while streaming.Jean-Francois Moine

2008-09-03V4L/DVB (8720): gspca: V4L2_CAP_SENSOR_UPSIDE_DOWN added as a cap for some ↵Hans de Goede
webcams. This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags, and sets this flag for the Philips SPC200NC cam (which has its sensor installed upside down). The same flag is also needed and added for the Philips SPC300NC. Together with a patch to libv4l which adds flipping the image in software this fixes the upside down display with the SPC200NC cam.
