Fix all device drivers to use the video_drvdata function instead of
maintaining a local list of minor to private data mappings. Call
video_set_drvdata to register the driver private pointer when not
already done.
Where applicable, the local list of mappings is completely removed when
it becomes unused.

Randy Dunlap <randy.dunlap@oracle.com> reported a breakage while compiling
drivers/staging/tm6000, due to this change:
commit 1c1b78bee1a94f98deeb9c24b21c4812e191646c
Author: Greg Kroah-Hartman <gregkh@suse.de>

USB: remove unused usb_buffer_alloc and usb_buffer_free macros
Now that all callers are converted over, remove the compatibility
functions and all is good.
As the function got renamed, the rename should also be applied at
tm6000.

The values for the fourcc format were correct, but applied to the
wrong register. With this change, video is now barely working again with
tm6000.
While here, let's remove, for now, the memset. This way, people can
have some image when testing this device.
Yet to be fixed: parts of the image frame are missed. As we don't clean
the buffers anymore, this is "recovered" by repeating the values from a
previous frame. The quality is bad, since the image pixels will contain
data from some previous frames, generating weird delay artifacts.

Changing a video standard takes a long time to happen on tm6000, since it
needs to load another firmware, and the i2c implementation on this device
is really slow. When the driver tries to change the video standard, a
kernel panic is produced:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
IP: [<ffffffffa0c7b48a>] tm6000_irq_callback+0x57f/0xac2 [tm6000]
...
Kernel panic - not syncing: Fatal exception in interrupt
By inspecting it with gdb:
(gdb) list *tm6000_irq_callback+0x57f
0x348a is in tm6000_irq_callback (drivers/staging/tm6000/tm6000-video.c:202).
197 /* FIXME: move to tm6000-isoc */
198 static int last_line = -2, start_line = -2, last_field = -2;
199
200 /* FIXME: this is the hardcoded window size
201 */
202 unsigned int linewidth = (*buf)->vb.width << 1;
203
204 if (!dev->isoc_ctl.cmd) {
205 c = (header >> 24) & 0xff;
206
Clearly, it was the trial to access *buf, at line 202 that caused the
Panic.
As ioctl is serialized, While S_STD is handled,QBUF/DQBUF won't be called.
So, the driver will run out of the buffers, and *buf will become NULL.
As, on tm6000, the same URB can contain more than one video buffer, it is
likely to hit a condition where no new buffer is available whily copying
the streams. The fix is to leave the URB copy loop, if there's no more buffers
are available.
The same bug could also be produced by an application that is not fast enough
to request new video buffers.
The same bug were reported by Bee Hock Goh <beehock@gmail.com>.

Although the code is getting the better alternates, it is not really using
it. Get the interface/alternate numbers and use it where needed.
This patch implements also one small fix at the last_line set, as
proposed by Bee Hock Goh <behock@gmail.com>.

The driver was doing malloc when buf is null causing memory corruption.
The analog part is still pretty much broken but at least fixing this
will stop it from crashing the machine when streamon.

Instead of using magic pairs of req/reg, replace them by the defined
values.
This patch were generated by the following script:
cat tm6000-regs.h |perl -ne 'if (m/(TM6010_REQ[^\s]+)\s+0x([a-f0-9]+)\,
0x([a-f0-9]+)/) { $name="$1"; $req=$2; $val=$3; printf
"s/REQ_${req}_SET_GET_AVREG[_BIT]*, 0x[0]*$3,/$1,/\n" }' >a; for i in
tm*.c; do sed -f a $i >b && mv b $i; done

Now that the video_device registration is tested using
video_is_registered(), drivers don't need to initialize the
video_device::minor field to -1 anymore.

Instead of using the minor number in kernel log messages, use the device
node name as returned by the video_device_node_name() function. This
makes debug, informational and error messages easier to understand for
end users.

if a transfer buffer allocation fails, the last allocated urb is leaked
(it hasn't been stored in dev->urb[] yet so tm6000_uninit_isoc misses
it). The patch also includes a small typo fix.

Previously, there were no sync between video buffer filling and received
URBs. So, the presented image were a mix of frame and frame-1. Now, a
filled buffer should contain only data for that frame.
allocates a maximum of 64 KB per each URB area. This fixed two bugs:
- Sometimes, there were no available continuos block of about 1 MB;
- Image weren't not properly updated, since parts of the URBs aren't
updated.

Adds a driver for Trident TV Master tm5600/tm6000 chips.
Those USB devices are usually found with a Xceive xc2028/xc3028
tuner, although the firmware seems to be modified to work with
those chips on some older devices.
