i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58+00:00

I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

V4L/DVB: ivtv: Timing tweaks and code re-order to try and improve stability

2010-06-01T04:24:35+00:00

Added small delay on device open & close to allow hardware to settle. Move yuv
register restore to before the decoder firmware call to stop playback.

V4L/DVB: ivtv: Avoid accidental video standard change

2010-06-01T04:24:33+00:00

For yuv video output, pass fake values to avoid firmware trying to change
video standard.

V4L/DVB: ivtvfb : Module load / unload fixes

2010-06-01T04:24:32+00:00

Check firmware state when loading module & if firmware is not responding exit
with an error. When module is unloaded, only disable the framebuffer & not all
decoder output.

V4L/DVB: cx2341x: Report correct temporal setting for log-status

2010-06-01T04:24:31+00:00

[Andy Walls comment:] This patch from Ian removes the cx2341x module lying
about the setting of the temporal filter for the log status ioctl().

V4L/DVB: drivers/media: Eliminate a NULL pointer dereference

2010-06-01T04:24:22+00:00

In each case, the print involves dereferencing a value that is NULL or is
near NULL.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@r exists@
expression E,E1;
identifier f;
statement S1,S2,S3;
@@

if ((E == NULL && ...) || ...)
{
  ... when != if (...) S1 else S2
      when != E = E1
* E->f
  ... when any
  return ...;
}
else S3
//

V4L/DVB: dvb-core: Fix ULE decapsulation bug

2010-06-01T04:24:21+00:00

Fix ULE decapsulation bug when less than 4 bytes of ULE SNDU is packed
into the remaining bytes of a MPEG2-TS frame

ULE (Unidirectional Lightweight Encapsulation RFC 4326) decapsulation
code has a bug that incorrectly treats ULE SNDU packed into the
remaining 2 or 3 bytes of a MPEG2-TS frame as having invalid pointer
field on the subsequent MPEG2-TS frame.
