V4L/DVB (9796): drivers/media/video/cx88/cx88-alsa.c: Adjust error-handling code
In the function cx88_audio_initdev, the value card has been created using
snd_card_new. The other error handling code in this function frees the
value using snd_card_free. I have thus changed the first error case to do
the same. On the other hand, it may be that card is not sufficiently
initialized at this point to use snd_card_free, in which case something
else should be done to free the memory in the error case.
In the function snd_cx88_create the call kfree(chip) in one error case
looks suspicious, both because it is not done in the other error code, and
because chip points into the middle of the memory allocated by
snd_card_new, ie it is not itself associated with a separate kmalloc.
Therefore I have removed it.

A major rewrite of interrupt handling for incoming mailbox processing, to split
the timing critical steps from the the deferrable steps as the sending XPU on
the CX23418 will time out and overwrite our incoming mailboxes rather quickly.
Setup a pool of work "order forms" for the irq handler to send jobs to the new
work handler routine which uses the kernel default work queue to do the
deferrable work. Started optimizing some of the cx18-io calls as they are now
the low hanging fruit for recoving microseconds back from the timeline.

combine smaller functions in the irq path into the larger ones to save ~2 us

V4L/DVB (9712): gspca:Subdriver ov534 added.
The OmniVision OV534 is the USB bridge chip used in Sony Playstation EYE,
it is found also in other webcams like Hercules Blog Webcam and
Hercules Dualpix HD.
This driver is the port to gspca of a prototype driver by Mark Ferrell
based on vivi. The original code to initialize the camera and start the
capture is from Jim Paris on ps2dev.org, here integrated with the analysis
of the USB communications taken by the windows driver.
