In commit a3d6e8cc gspca_dev->dev is set to NULL on disconnect, before calling stop0. The plan was to get rid of gspca_dev->present and instead simply check for gspca_dev->dev everywhere where we were checking for present. This should be race free since all users of gspca_dev->dev hold the usb_lock, or so I thought. But I was wrong, drivers which use a work-queue + synchronous bulk transfers to get the video data don't hold the usb_lock while doing so, their stop0 callbacks stop the workqueue, so they won't be using gspca_dev->dev anymore after the stop0 call, but they might be dereferincing it before, so we should not set gspca_dev->dev to NULL on disconnect before calling stop0. This also means that the workqueue functions in these drivers cannot use gspca_dev->dev to check if they need to stop because of disconnection, so we will need to keep gspca_dev->present around, and set that to 0 on disconnect, before calling stop0. Unfortunately as part of the plan to remove gspca_dev->present, these workqueues where already moved over to checking for gspca_dev->dev instead of gspca_dev->present as part of commit 254902b0, so this patch also reverts those parts of that commit.

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.

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: NHans Verkuil <hans.verkuil@cisco.com> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

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.

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.
