streamzap uses 'struct timeval' to store the start time of a signal for
gap tracking. struct timeval uses a 32-bit seconds representation which
will overflow in year 2038 and beyond. Replace struct timeval with ktime_t
which uses a 64-bit seconds representation and is 2038 safe. This patch
uses ktime_get_real() preserving the use of wall-clock time in the

The Terratec Cinergy T XS is a DVB-T receiver with no analog TV tuner.
This patch adds support for the cards carrying the mt2060 tuner; it's
unclear whether there are cards sold under the same name which use a
different tuner.
As long as there are no reports of such cards, and indeed as long as
there are no working drivers for them, we assume that the USB device

Many decoders require a trailing space (period without IR illumination)
to be delivered before completing a decode.
Since the gpio-ir-recv driver only delivers events on gpio transitions,
a single IR symbol (caused by a quick touch on an IR remote) will not
be properly decoded without the use of a timer to flush the tail end
state of the IR receiver.
This patch initializes and uses a timer and the timeout field of rcdev
to complete the stream and allow decode.
The timeout can be overridden through the use of the LIRC_SET_REC_TIMEOUT
ioctl.

The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).
So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
But this means that OF-only drivers needs to have both OF and SPI id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.
To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.
