commit 8c5bcded11cb607b1bb5920de3b9c882136d27db upstream.
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]

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.

Let's use it in right order.

- 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().

Since b9bf2eafaad9c1ef02fb3db38c74568be601a43a, 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.
