Add support for design which has an em2863/tvp5150 and uses the standard
empia USB ID. In Sander's case, it was branded as an "Eminent model EM3705"
Thanks to Sander Van Ginkel for testing and help debugging the support.

This patch enables the anti-alias filter, which was originally enabled for

Rework the logic for tracking the amount of data copied to the VBI buffer, to
address problem found where the video lines are several bytes shifted to the
right (and the leading pixels in the first line rendered are garbage). This
would occur because the copy function would advance the pointer when detecting
headers, but the caller would not adjust the length actually copied.

Increase the packets per URB count from 40 to 64. I suspect that whoever was

In quickcam_messenger.c, if the NULL test on uvd is needed, then the
dereference should be after the NULL test.
In vpif_display.c, std_info is initialized to the address of a structure
field. This seems unlikely to be NULL. Test std_info->stdid instead.
In saa7134-alsa.c, the function is only called from one place, where the
chip argument has already been dereferenced. On the other hand, if it
should be kept, then card should be initialized after it.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
// <smpl>
@match exists@
expression x, E;
identifier fld;
@@
* x->fld
... when != \(x = E\|&x\)

According with the original patch that added the register names, those
are related to tm6010, so name it properly as such. Also, clearly
indicates when a register belongs to Request 0x08 and add its register
value at the name. This makes easier to double check if the proper
register is used along the driver.
This patch were made with the help of this simple perl script, applied
over the definitions of the last register groups:
if (m/define (TM6000_)([^\s]+)\s+0x([A-F0-9].)/) { $name=$2;
$val=$3; printf "s,$1$2,TM6010_REQ08_R%s_%s,g\n", $val, $name; }
And were manually adjusted to fix a few minor issues.
