The fast firmware load hack in cx25840 uses private data. In fact, it
breaks pvrusb2 and doesn't work at all with ivtv. It is a unsafe
implementation and so it is removed.

This patch prevents a bug where the frontend is unable to tune after waking
from powered down state. Now, the device remains powered on until it is
disconnected, just like the windows driver. It seems that the bluebird
firmware is unable to successfully handle tuning after a powered down state.
This patch fixes all of the FusionHDTV Bluebird USB2 devices. The Medion
MD95700 will still behave as before, since it was unaffected by this bug.

- fixed the reception of channels with low symbol rates.

  symbol rates from 1 to 5 MSps do not work. I changed them
  to values found experimentally. The charge pump current
  and FILTUNE voltage are now set to values recommended in

It looks like the HD3000 was prototyped with the 7610 tuner when
the driver was developed, but the cards appear to have always shipped
with the 7612 tuner and the driver was never adjusted for it.
The definition needs to be corrected.

This mutex is meant to stop two devices getting the same ID. dvbdev_get_free_id() 
scans the list of already allocated devices to find a free id.
Unfortunately, since the mutex is unlocked before the card is added to the
above list, it is still possible for two of them to get the same id.
Its debatable whether this mutex lock is actually needed, but I'm unwilling
to just remove it in case something does depend on it.

There are tree mistakes on bttv_risc_overlay.
1) When skip_odd is true, the number of lines for which
instructions are written is (height+1)/2, not height/2.
2) This occurs when clipping: the number of instruction bytes
written can be as much as 8 + 12*nclips, not 8 + 8*nclips, as
currently estimated.
3) Coverity check were wrong with nskips=0, since it means that
it can clipped at most one line.

If the device is disconnected while serial_open() is executing and
either try_module_get() or the device specific open function fails, the
kref_put() call in the 'bailout_kref_put' label will free the memory
pointed out by 'port'.

The subsequent dereferences in the 'bailout_kref_put' label will be
invalid.

The fix is just to assure kref_put() is called after any 'port' usage.

It's become apparent as machines get faster that the emagic kernel firmware
loaders (based on the ezusb loader) have a reset race.  a 400MHz TiBook
never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
time.  The bug is seen as a hung USB box and the kernel error:

drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
error = -110

The patch below inserts a delay after deasserting reset to allow the box to
settle before a new command is issued.  This affects only device startup.

661FX7MI-S motherboard which uses the SiS 661FX chipset.  The patch adds
an entry to mii_chip_info for the transceiver.

The PHY ids were found using the sis900_c_122.diff patch from
http://brownhat.org/sis900.html but that patch didn't solve the problem,
because the PHY at address 1 was already being chosen.

Without my patch, when bursts of packets arrive from other hosts on a
LAN, the interface dropped one roughly 10% of the time, causing
retransmits.  There were fifth second pauses in refresh of large xterms,
and it made Netrek suck.  I can provide further test data.

Workaround in lieu of patch is to use mii-tool to advertise
100baseTx-HD, then force renegotiation.

I wasn't able to identify the actual transceiver, so the description
field is a guess.

This patch is similar to Artur Skawina's patch:
http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2

I'm not sure, but I wonder if it means the default behaviour should be
changed, so as to better handle future transceivers.
