This is the first in a series of three patches to convert the ov511
driver's /proc/video interface to sysfs. All V4L drivers must undergo
this conversion now that /proc/video has been removed from the core.
This patch removes ov511's /proc/video support, which allows it to

Now that I mentioned that inserting usb-storage hangs forever
and then causes a SCSI oops, the question arises how the hang
is caused. It turns out to be a semaphore deadlock.
What happens is that base/bus.c:bus_add_driver() downs

Recently we've seen some oopses reported in code that cleaned
up HCs after they died ... like pci-pm not letting ohci-hcd
suspend until after the hardware was partly disabled, or users
removing a Cardbus adapter with ehci-hcd. One root cause was
that the cleanup called hcd->stop() too many times.
I see an Oops in the SCSI code, caused by the fact that sdkp is NULL
in sd_shutdown. "How can that be?", you will ask - dev->driver_data was set
in sd_probe. But in my case sd_probe never finished. An insmod usb-storage
hangs forever, or at least for more than six hours, giving ample opportunity

It gets a big thumbs-up from me. I tried it on 2.6.0-test3 both with and
without preemption, and it works well. Thanks!

I've got a plan for reorganizing usb_reset_device(),
usb_set_configuration(), and parts of the hub driver and core. Although
it's a bit elaborate, it shouldn't have any visible consequences for
drivers -- except that these routines will start working the way people
want.

Okay, I see the problem with 2.6. It stems from a chang
