Ulrich Eckhardt 8c5bcded11 [media] ds3000: fix LNB supply voltage on Tevii S480 on initialization
The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not
automatically power down. This blocks other receivers connected
to a satellite channel router (EN50494), since the receivers can not send the
required DiSEqC sequences when the Tevii card is connected to a the same SCR.

This patch switches off the LNB supply voltage on initialization of the frontend.

[mchehab@osg.samsung.com: add a comment about why we're explicitly
 turning off voltage at device init]

Heinrich Schuchardt b59de95bed [media] ds3000: fix reading array out of bound in ds3000_read_snr
An attempt was made to read dvbs2_snr_tab[80],
though dvbs2_snr_tab has only 80 elements.

Malcolm Priestley a0a030bdbe [media] ts2020: call get_rf_strength from frontend
Restore ds3000.c read_signal_strength.
Call tuner get_rf_strength from frontend read_signal_strength.
We are able to do a NULL check and doesn't limit the tuner
attach to the frontend attach area.
At the moment the lmedm04 tuner attach is stuck in frontend
attach area.

Rémi Cardona d58f4f2728 [media] ds3000: bail out early on i2c failures during firmware load
- if kmalloc() returns NULL, we can return immediately without trying
   to kfree() a NULL pointer.
 - if i2c_transfer() fails, error out immediately instead of trying to
   upload the remaining bytes of the firmware.
 - the error code is then properly propagated down to ds3000_initfe().

Rémi Cardona b41a536cf9 [media] ds3000: remove useless 'locking'
Since b9bf2eafaa, the function
ds3000_firmware_ondemand() is called only once during init. This
locking scheme may have been useful when the firmware was loaded at
each tune.
Furthermore, it looks like this 'lock' was put in to prevent concurrent
access (and not recursion as the comments suggest). However, this open-
coded mechanism is anything but race-free and should have used a proper
mutex.
