On my AverMedia AverTV Studio 507, key up events are no longer sent after

Thank you for your feedback. It makes a lot of sense.
Changing it is not a problem :)
How about the updated patch below?
If the memory allocation to 'state' succeeds but we jump to the 'error'
label before 'state' is assigned to fe->tuner_priv, then the call to
'zl10036_release(fe)' at the 'error:' label will not free 'state', but
only what was previously assigned to 'tuner_priv', thus leaking the memory
allocated to 'state'.
This patch fixes the leak and also does not jump to 'error:' before mem
has been allocated but instead just returns. Also some small style
cleanups.

[media] af9015: enhance RC
Patch from Ian Armstrong.
I've encountered a couple of problems with the current af9015 driver as
supplied with the 2.6.37 kernel, that the attached patch appears to fix. (I've
generated this patch against the current v4l-dvb git).
Some key-presses are lost. A key-press is only generated upon 'valid' data
(buf[14] == (u8) ~buf[15]), but the buffer is wiped before this check.
Sometimes the 15th byte has not been set at the time of read, so the data
isn't valid & ignored. On the next poll the 15th byte has been set, but the
rest of the data was wiped previously, so the data is still invalid & the key
is lost.
Weird repeat error, where an old key press is sometimes repeated in error. ie.
button sequence '1 (pause) 2 (pause) 3 (pause) 4' generates output like '1
(pause) 2 (pause) 23 (pause) 4'. The current driver zeroes the data for the
key pushed, but sometimes this data is already zero but with other bytes set
suggesting a repeat code. This results in the last key being incorrectly
repeated.
This patch attempts to reduce the risk of a missed key-press & also stop the
random repeat of an old key-press when a new key is pressed.

[media] v4l: v4l2_subdev userspace format API
Add a userspace API to get, set and enumerate the media format on a
subdev pad.
The format at the output of a subdev usually depends on the format at
its input(s). The try format operation is thus not suitable for probing
format at individual pads, as it can't modify the device state and thus
can't remember the format tried at the input to compute the output
format.
To fix the problem, pass an extra argument to the get/set format
operations to select the 'try' or 'active' format.
The try format is used when probing the subdev. Setting the try format
must not change the device configuration but can store data for later
reuse. Data storage is provided at the file-handle level so applications
probing the subdev concurently won't interfere with each other.
The active format is used when configuring the subdev. It's identical to
the format handled by the usual get/set operations.
