V4L/DVB (9472): dm1105: fix the misuse of pci_dma_mapping_error
pci_dma_mapping_error can't be used for pci_alloc_consistent
(pci_dma_mapping_error is for dma_map_single and dma_map_page).
pci_alloc_consistent returns NULL if the allocation fails.

V4L/DVB (9462): Allow specifying clock per device
Optimizations galore: Blistering barnacles! The KNC1 and friends
like 90 Mhz clock much better rather than running at a higher
throttle, for almost similar hardware. he exact cause unknown,
possibly due to a lower voltage applied for the demod power supply.

V4L/DVB (9443): Bug: Bandwidth calculation
Bug #1: The 5 tap equaliser is set to correct simple perturbations
like reflections on the IF cable for DVB-S. In the case of DVB-S2
a more powerful equalizer is used to correct the filter group delay
allowing the bandwidth to be reduced by a factor of 1/3
Bug #2: The ZIF tuner takes badwidth to be set in Hz

V4L/DVB (9442): Revert back previous change to 90MHz
Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
incoming symbols and hence might run into problems at the very end of the
specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
running at 90MHz, raises lot of issues such as the need to recalculate
all of them , which is eventually very painful.

In this case, we will be sure that there exists a carrier

a circumstance, the TR loop is simplified to doing a simple

BUG! Setting CRL parameter overwrote the CR Algorithm type,
eventually leading to wrong search algorithm to be employed in
the DVB-S carrier loop optimization.
Symptom: Once the CR optimization stage is passed either way, in
a successful or failed manner, the very next carrier search will
fail, due to no Carrier Search Algorithm specified.

V4L/DVB (9381): On the KNC1 cards the CLOCK is clamped to a maximum limit of 90MHz, eventhough
not limited in hardware, this causes instabilities at a higher clock due to
issues such as thermal, also the divider wraps around, which causes the
demodulator core to actually run at a lower frequency. This needs to be
empirically tested whether it affects other cards. If found necessary, this
parameter needs to be moved out to the config struct such that it can be made
hardware dependant.
Reducing the CLOCK from 99MHz to 90MHz improved the acquisition time taken on
the KNC1 cards and hence such a change.
