793786d19a V4L/DVB (11782): Siano: smsdvb - use 'push' status mechanism
This patch replace the old method of pulling the device status by
sending "get_statistics" request, to push mode. This make status update
much faster, and reduce various operation time (UHF scan now takes 15s
instead of 2m). In order to make the change the following modification
have been applied:
1) core header - update statistics headers.
2) dvb adapter - omit the statistics request, add handling of
status indications.
3) core 'onresponse' - re-route messages addressed to other adapter
to the dvb adapter.

a5beb7b323 V4L/DVB (11875): dvb_frontend: fix case where fepriv->exit not reset
The fact that we now explicitly set fepriv->exit = 1 when the thread is
shutting down exposed an edge case where it was not being reset back to zero
once the thread went away in some cases.  This resulted in failures in cases
where the frontend was closed, and then opened O_RDONLY, since in that case
the thread is not being restarted but it was checking the fepriv->exit flag.

Thanks to Thierry Lelegard, who and encountered and debugged a large portion
of the issue in the same twelve hours that I did (as well as testing my patch).

57594a586f V4L/DVB (11785): dvb_frontend: fix race condition resulting in dropped tuning commands
A race condition was detected in the case that putting the tuner to sleep takes
an unusually long period of time, combined with applications that quickly
close/open the dvb frontend.

The kaffeine channel scanner closes and reopens the dvb frontend between each
tuning attempt.  If it takes an unusually longer period of time to put the
tuner to sleep (for example, the Pinnacle 801e takes 660 ms), the dvb_frontend
thread will still be in a running state (and hence fepriv->thread is still set)
but the fepriv->exit field will still be zero.  As a result, if a
dvb_frontend_start() call arrives while the frontend thread is in the process
of terminating, the call will return 0 without actually starting a new thread.
This results in the tuning request being dropped.

To address this, mark fepriv->exit as soon as we know the thread is going to
be terminated, so that dvb_frontend_start() knows to start a new instance.

Problem encountered with Kaffeine 0.8.7 doing ATSC scanning against the
Pinnacle 801e tuner, in conjunction with new code to power down the xc5000
when not in use.

1e7439388a V4L/DVB (11999): af9015: fix stack corruption bug
This patch fixes stack corruption bug present in af9015_eeprom_dump():
the buffer buf is one byte smaller than required - there is 4 chars
for address prefix, 16*3 chars for dump of 16 eeprom bytes per line
and 1 byte for zero ending the string required, i.e. 53 bytes, but
only 52 are provided.
The one byte missing in stack based buffer buf causes following oops
on MIPS little endian platform, because i2c_adap pointer in
af9015_af9013_frontend_attach() is corrupted by inlined function
af9015_eeprom_dump():

The frontend attachment code didn't handle cases where the frontend
partially failed to attach.  For instance, when the demod was attached
successfully but the tuner driver wasn't compiled or fails to init for some
reason.  In these cases we try to clean up the partial attachment and fail
instead of proceeding with a broken frontend.

If frontend registration fails, clean up with dvb_frontend_detach() rather
than just calling the frontend's main release method.  The former does some
additional stuff, like release an attached tuner and take care of putting
symbols when dynamic binding is used.

In skystar2_rev23_attach() it's not necessary to set fc->dev_type, that
gets set before skystar2_rev23_attach() is called.

eda9f7523b V4L/DVB (11841): core: fix potential mutex_unlock without mutex_lock in dvb_dvr_read
dvb_dvr_read may unlock the dmxdev mutex and return -ENODEV, except this
function is a file op and will never be called with the mutex held.

There's existing mutex_lock and mutex_unlock around the actual read but
it's commented out.  These should probably be uncommented but the read
blocks and this could block another non-blocking reader on the mutex
instead.

This change comments out the extra mutex_unlock.

86cf5f84e6 V4L/DVB (11833): dvb-usb: Remove support for Genpix-CW3K (damages hardware)
I have been informed by the manufacturer that the patch currently in the v4l tree to support the Genpix-CW3K version of the hardware will actually
damage the firmware on recent units.  As he seems to not want this hardware supported in Linux, and I do not know how to detect the difference between
affected and not-affected units, I am requesting the immediate removal of support for this device.  This patch removes a portion of the changeset
dce7e08ed2b1 applied 2007-08-18 relating to this specific device.

Adapted patch to not remove code, but to only to comment it out.

81dae6716f V4L/DVB (11832): dibusb_mc: fix i2c to not corrupt eeprom in case of strange read pattern
dibusb_i2c_xfer seems to do things very dangerous :
it assumes that it get only write/read request or write request.

That means that read can be understood as write. For example a program
doing
file = open("/dev/i2c-x", O_RDWR);
    ioctl(file, I2C_SLAVE, 0x50)
read(file, data, 10)
    will corrupt the eeprom as it will be understood as a write.
