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.

V4L/DVB (9598): cx18: Prevent CX23418 from clearing it's outgoing ack interrupts to driver
When the CX23418 CPU unit sent out an ack interrupt to the linux driver, it
also received that interrupt and cleared the flag before the linux driver could
see what the interrupt was for. This fix prevents the CPU from receiving an
IRQ for it's own outgoing ack's to the linux driver. This fix is critical now
that the linux driver doesn't poll but relies on these ack interrupts.
