The exchanges for sensor mt9v111 are different with bridges zc301 and zc303.
The exchanges for the bridge zc303 were those of the bad named tas5130ck.
These mt9v111 exchanges have been adjusted from the ms-Windows public files
vm30x.inf (for 0ac8:301b) and usbvm303.inf (for 0ac8:303b).

The new exchanges are extracted from the public file lPEPI264v.inf of the
ms-Windows driver. In this file, the sensor is named hv7131b but the exchanges
are those of the hv7131r.

- use an enum to define the sensor numbers
- use the sensor numbers to index the associated tables
- rename TAS5130CXX to TAS5130C
- rename HV7131C to HV7131R
- change some comments

Some webcams as ov511 may find many times an end of image.
In this case, with the last patch in image concatenation
(commit 799b1bd41f398054d46fd35f73abd01c4009f6ca),
the image pointer was NULL and the system crashed in memcpy().

The bit 0x04 of the bridge register 02 (GPIO) is used for audio connection

This patch fixes possible race conditions in queue management with SMP:
when a frame was completed, the irq function tried to use the next frame
buffer. At this time, it was possible that the application on an other
processor updated the frame pointer, making the image to point to a bad
buffer.
The patch contains two main changes:
- the image transfer uses the queue indexes which are protected against
simultaneous memory access,
- the image pointer which is used for image concatenation is only set at
interrupt level.
Some subdrivers which used the image pointer have been updated.

The problem may occur with SMP:
- a frame is completed at interrupt level (in gspca_frame_add with
packet_type == LAST_PACKET,
- just after clearing the bit V4L2_BUF_FLAG_QUEUED and before setting
the bit V4L2_BUF_FLAG_DONE, on the other processor, the application
tries to requeue the same frame buffer,
- then, the qbuf function succeeds because ALL_FLAGS are not set.
The fix sets and resets the two flags in one instruction.

The image pointer and its length are now in the main structure instead
of in the frame buffer. They are updated on application vidioc_qbuf and
in the URB interrupt function when ending an image.

Right, thanks for pointing this out!
Attached is the updated patch, please use this one instead.
Thanks!
Duplicate functionality with the gspca_zc3xx driver, zc0301 only
supports 2 USB-ID's (because it only supports a limited set of
sensors) wich are also supported by the gspca_zc3xx driver
(which supports 53 USB-ID's in total).

Use kmemdup when some other buffer is immediately copied into the
allocated region.
A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression from,to,size,flag;
statement S;
@@
- to = \(kmalloc\|kzalloc\)(size,flag);
+ to = kmemdup(from,size,flag);
if (to==NULL || ...) S
- memcpy(to, from, size);
// </smpl>

- 1 ms "msleep" applied to each sensor after USB control data exchange
This was done for two sensors because these exchanges were known to
be too quick depending on laptop model.
It is fairly logical to apply this delay to each sensor
in order to prevent from having errors with untested hardwares.
