[PATCH] USB ov511: Convert to new V4L 1 interface

Here's a patch to switch ov511 over to the new V4L 1 interface
introduced in 2.4.19. Rather than storing the function pointers for
open(), ioctl(), etc in struct video_device, I just hand the V4L layer a
struct file_operations.

The advantages of this are:

- The driver more closely resembles its 2.5 counterpart.

- Multiple simultaneous opens will eventually be possible.

- The old interfaces required calling video_unregister_device() from
close() if the device was unplugged while open, causing a deadlock in
the V4L layer. Now we just call video_unregister_device()
unconditionally from disconnect(). (Credit goes to Duncan Haldane for
tracking that bug down)

This is just a backport of the changes made to the driver in ~2.5.10;
nothing new here. I've been using this version of the code under 2.4 for
months and it works well.

[PATCH] USB scanner driver: updated documentation

This patch updates the documentation for the USB scanner driver. The
details:

Documentation/usb/scanner.txt:
- Added information about read_timeout
- Added more details about /proc/bus/usb/devices
- Added/updated links
- Added pointers two "special" scanner drivers
- Reordering, spell-checking, formatting
- Used /dev/usb/scanner[0-15] instead of /dev/usbscanner[0-15]
- Removed some basic USB configuration stuff
- Added EHCI
- Removed some more references to HP

Documentation/usb/scanner-hp-sane.txt:
Removed completely. This was a very outdated text for some HP
scanners. All of this is explained in the documentation of the
user-space SANE tools. Links and a short explanation about SANE was
added to scanner.txt instead.

[PATCH] usb semaphore lock in 2.4.20-rc1 (since 2.4.13)

This fixes an oops if cpia is built into the kernel along with USB.
cpia (in drivers/media/) inits before USB and causes use of an
uninitialized semaphore in USB.

Patch is from Duncan Haldane.

[PATCH] ehci updates

This patch basically brings the 2.4 code up to the level
of the latest 2.5.52bk4+ patches ... so while not perfect
(I know of a hub issue) I think it's worth circulating:

- Fixes "it hangs" ... at least for the storage cases
I could reproduce.

- Longer reset timeout for Intel EHCI ... this bug had
been lurking since July in the 2.5 series, but was
only reported (and most of the fix identified!) by a
user after 2.4.21pre1 came out.

- Better fixes for a problem first seen with VT8235.
Had to dedicate a QH as list head, never unlinked.
Oopsable, but NEC hardware seemingly implemented the
EHCI spec in a way that they didn't require that.

- Significant updates to QTD and URB queuing. Much
more robust, fewer hardware races. Uses "dummy td"
scheme. Most USB device drivers in 2.4 won't stress
that logic as much as usb-storage does in 2.5, but
the robustness should help all around.

- Diagnostics updates. Both 2.4 and 2.5 versions
should emit the same "new style" diagnostics,
but 2.4 can't use <linux/device.h> to do it.

- DaveM's "remove tasklet" patch. Bubbled up to the
"hcd" glue, but completions on 2.4 don't receive
the 'struct pt_regs *' so it stops there.

- Other less notable fixes and cleanups too.

One way to look at the patch is: (a) a smallish set
of "hcd" updates, which can help 2.4 backports of the
other 2.5 "*hcd" drivers too; (b) the 2.5 ehci-hcd with
the addition of about 4K of patches to handle things
like "2.4 needs interrupt automagic".
