4c07e32884 [media] xc4000: Fix get_frequency()
The programmed frequency on xc4000 is not the middle
frequency, but the initial frequency on the bandwidth range.
However, the DVB API works with the middle frequency.

This works fine on set_frontend, as the device calculates
the needed offset. However, at get_frequency(), the returned
value is the initial frequency. That's generally not a big
problem on most drivers, however, starting with changeset
6fe1099c7a, the frequency drift is taken into account at
dib7000p driver.

This broke support for PCTV 340e, with uses dib7000p demod and
xc4000 tuner.

e23cf7f358 [media] tuners/Kconfig: fix build when just DTV or SDR is enabled
As reported by Kbuildtest:
	warning: (VIDEO_PVRUSB2 && VIDEO_TLG2300 && VIDEO_USBVISION && VIDEO_GO7007 && VIDEO_AU0828_V4L2 && VIDEO_CX231XX && VIDEO_TM6000 && VIDEO_EM28XX && VIDEO_IVTV && VIDEO_MXB && VIDEO_CX18 && VIDEO_CX23885 && VIDEO_CX88 && VIDEO_BT848 && VIDEO_SAA7134 && VIDEO_SAA7164) selects VIDEO_TUNER which has unmet direct dependencies (MEDIA_SUPPORT && MEDIA_TUNER)

That happens when:

	# CONFIG_MEDIA_ANALOG_TV_SUPPORT is not set
	CONFIG_MEDIA_DIGITAL_TV_SUPPORT=y
	# CONFIG_MEDIA_RADIO_SUPPORT is not set
	# CONFIG_MEDIA_SDR_SUPPORT is not set
	CONFIG_VIDEO_AU0828_V4L2=y
	CONFIG_VIDEO_CX231XX=y
	CONFIG_VIDEO_TM6000=y
	CONFIG_VIDEO_EM28XX=y
	CONFIG_VIDEO_TUNER=y
	CONFIG_MEDIA_SUPPORT=y

With means that we need to enable MEDIA_TUNER also when DTV
is enabled. While the above config doesn't cover, if we enable
SDR, the same error can also happen.

f7a27ff1fb [media] xc5000: delay tuner sleep to 5 seconds
Some drivers, like au0828 are very sensitive to tuner sleep and may
break if the sleep happens too fast. Also, by keeping the tuner alive
for a while could speedup tuning process during channel scan. So,
change the logic to delay the actual sleep to 5 seconds after its
command.

ebf044f46f [media] tuner-xc2028: Don't try to sleep twice
Only send a power down command for the device if it is not already
in power down state. That prevents a timeout when trying to talk
with the device.

58f087c9b6 [media] e4000: fix error return code
Set the return variable to an error code as done elsewhere in the function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

// </smpl>
