That doesn't make much sense. What the driver is actually trying
to do is to divide one second by a value. So, check the range
before dividing. That warrants the right result and will remove
the warnings on non-64 bits archs.
Also fixes this warning:
drivers/media/platform/sti/bdisp/bdisp-debug.c:588: warning: comparison of distinct pointer types lacks a cast
by using div64_s64() instead of calling do_div() directly.

The embedded UART is apparently used to receive decoded IR (RC5?) codes.
Forward these scan codes to the RC framework and (where known) add
corresponding mapping tables to translate them into regular keys.
This patch has been tested on a TechniSat CableStar HD2. The mappings of other
rc-maps were taken from Christoph Pinkl's patch
(http://patchwork.linuxtv.org/patch/7217/) and the s2-liplianin repository. The
major difference to Christoph's patch is a reworked interrupt handling of the
UART because the RX interrupt is apparently level triggered and requires
masking until the FIFO is read by the UART worker.

In little endian cases, macro cpu_to_be16 unfolds to __swab16 which
provides special case for constants. In big endian cases,
__constant_cpu_to_be16 and cpu_to_be16 expand directly to the
same expression. So, replace __constant_cpu_to_be16 with
cpu_to_be16 with the goal of getting rid of the definition of
__constant_cpu_to_be16 completely.
The semantic patch that performs this transformation is as follows:
@@expression x;@@
- __constant_cpu_to_be16(x)

Provide a DVBv5 API signal strength. This is in units of 0.001 dBm rather
than a percentage.
>From Antti Palosaari's testing with a signal generator, it appears that the
gain calculated according to Montage's specification if negated is a
reasonable representation of the signal strength of the generator.
To this end:
(1) Polled statistic gathering needed to be implemented in the TS2020 driver.
This is done in the ts2020_stat_work() function.
(2) The calculated gain is placed as the signal strength in the
dtv_property_cache associated with the front end with the scale set to
FE_SCALE_DECIBEL.
(3) The DVBv3 format signal strength then needed to be calculated from the
signal strength stored in the dtv_property_cache rather than accessing
the value when ts2020_read_signal_strength() is called.

The TS2020 and TS2022 tuners take an input from the demodulator indicating the
AGC setting on that component that is then used to influence the tuner's own
gain. This should be taken into account when calculating the gain and signal
strength.
Further, the existing TS2020 driver miscalculates the signal strength as the
result of its calculations can exceed the storage capacity of the 16-bit word
used to return it to userspace.
To this end:
(1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that
the tuner can call to get the AGC PWM value from the demodulator.
(2) Modify the TS2020 driver to calculate the gain according to Montage's
specification with the adjustment that we produce a negative value and
scale it to 0.001dB units (which is what the DVBv5 API will require):
(a) Callback to the demodulator to retrieve the AGC PWM value and then
turn that into Vagc for incorporation in the calculations. If the
callback is unset, assume a Vagc of 0.
(b) Calculate the tuner gain from a combination of Vagc and the tuner's RF
gain and baseband gain settings.
(3) Turn this into a percentage signal strength as per Montage's
specification for return to userspace with the DVBv3 API.
(4) Provide a function in the M88DS3103 demodulator driver that can be used to
get the AGC PWM value on behalf of the tuner.
(5) The ts2020_config.get_agc_pwm function should be set by the code that
stitches together the drivers for each card.
For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022,
set the get_agc_pwm function to point to m88ds3103_get_agc_pwm.
I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022.
Thanks to Montage for providing access to information about the workings of
these parts.

struct timeval uses a 32-bit seconds representation which will
overflow in the year 2038 and beyond. This patch replaces
the usage of struct timeval with ktime_t which is a 64-bit
timestamp and is year 2038 safe.
This patch is part of a larger attempt to remove all instances
of 32-bit timekeeping variables (timeval, timespec, time_t)
which are not year 2038 safe, from the kernel.

The flexcop bridge chip has two banks of hardware pid filters -
an initial 6, and on some chip revisions an additional bank of 32.
A bug is present on the initial 6 - when changing transponders
one of two PAT packets from the old transponder would be included
in the initial packets from the new transponder. This usually
transpired with userspace programs complaining about services
missing, because they are seeing a PAT that they would not be
expecting. Running in full TS mode does not exhibit this problem,
neither does using just the additional 32.
This patch adds in an option to not use the inital 6 and solely use
just the additional 32, and enables this option for the SkystarS2
card. Other cards can be added as required if they also have
this bug.

My static checker detected that free_irq() is called even after
request_irq() failed in ddb_probe(). In this case, the kernel may try to
free dev->pdev->irq although the IRQ is not assigned. This event rarely
occurs, but always introduces a warning if it happens.
"goto fail1" always results in disabling enabled MSI and releasing a
requested IRQ. It seems like the former handling is necessary. So I added
a conditional branch before the free_irq() (stat == 0 means request_irq()
succeeds).
