[media] gspca: Add reset_resume callback to all sub-drivers

2012-07-30T21:39:22+00:00

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.

[media] gspca: the field 'frozen' is under CONFIG_PM

2012-05-20T12:35:42+00:00

The gspca_dev field 'frozen' is added only if CONFIG_PM is set. So add the relevant #ifdef's to various subdrivers that use it. The m32r daily build caught this mistake. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] gspca: Fix locking issues related to suspend/resume

2012-05-14T12:28:39+00:00

There are two bugs here: first the calls to stop0 (in gspca_suspend) and gspca_init_transfer (in gspca_resume) need to be called with the usb_lock held. That's true for the other places they are called and it is what subdrivers expect. Quite a few will unlock the usb_lock in stop0 while waiting for a worker thread to finish, and if usb_lock isn't held then that can cause a kernel oops. The other problem is that a worker thread needs to detect that it has to halt due to a suspend. Otherwise it will just go on looping. So add tests against gspca_dev->frozen in the worker threads that need it. Hdg, 2 minor changes: 1) The finepix device is ok with stopping reading a frame halfway through, so add frozen checks in all places where we also check if we're still streaming 2) Use gspca_dev->dev instead of gspca_dev->present to check for disconnect in all touched drivers. I plan to do this everywhere in the future, and most relevant lines in the touched drivers are already modified by this patch.

USB: convert drivers/media/* to use module_usb_driver()

2011-11-18T17:46:12+00:00

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.

[media] gspca - sq905c: Adds the Lego Bionicle

2010-12-29T10:17:05+00:00

This patch adds the Vendor:Product number of the Lego Bionicle camera to the existing gspca/sq905c.c and also a line for the camera in gspca.txt. The camera works "out of the box" with these small changes. So this is just in time for Christmas. Think of the children.
