In order to better organize the header file, move the legacy
API (DVBv3) support to the end, just before the ioctl definitions.
This way, we can use just one #if for all of them.

The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.
So, let's do it.
This patch was generated by this shell script:
for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done
While here, make CodingStyle fixes on the affected lines.

Extend detect_cvt/gtf API to indicate the format type (interlaced
or progressive). In case of interlaced, the vertical front and back
porch and vsync values for both (odd,even) fields are considered to
derive image height. Populated vsync, vertical front, back porch
values in bt timing structure for even and odd fields and updated
the flags appropriately.
Also modified the functions calling the detect_cvt/gtf(). As of now
these functions are calling detect_cvt/gtf() with interlaced flag

In mesh mode there is a race between establishing links and processing
rates and capabilities in beacons. This is very noticeable with slow
beacons (e.g. beacon intervals of 1s) and manifested for us as stations
using minstrel when minstrel_ht should be used. Fixed by changing
mesh_sta_info_init so that it always checks rates and such if it has not
already done so.

Channels in 2.4GHz band overlap, this means that if we
send a probe request on channel 1 and then move to channel
2, we will hear the probe response on channel 2. In this
case, the RSSI will be lower than if we had heard it on
the channel on which it was sent (1 in this case).
The scan result ignores those invalid values and the
station last signal should not be updated as well.
In case the scan determines the signal to be invalid turn on
the flag so the station last signal will not be updated with
the value and thus user space probing for NL80211_STA_INFO_SIGNAL
and NL80211_STA_INFO_SIGNAL_AVG will not get this invalid RSSI
value.

3. connect vif1 to the AP
4. connect vif2 to the AP
(auth fails because ath10k firmware isn't able

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also set IRQ_NOPROBE and this has been maintained although it is not
clear that is really needed. There appears to be a great deal of blind
copy and paste of this code.
