Dan Carpenter 3a9888f913 [media] ds3000: using logical && instead of bitwise &
The intent here was to test if the FE_HAS_LOCK was set.  The current
test is equivalent to "if (status) { ..."

Mauro Carvalho Chehab 7581e61d8d [media] dvb: Remove ops->info.type from frontends
Now that this field is deprecated, and core generates it for
DVBv3 calls, remove it from the drivers.

It also adds .delsys on the few drivers where this were missed.

Mauro Carvalho Chehab 7e0722215a [media] dvb-core: Don't pass DVBv3 parameters on tune() fops
As all parameters are passed via DVBv5 to the frontends, there's
no need to pass them again via fops. Also, most drivers weren't using
it anyway. So, instead, just pass a parameter to indicate if the
hardware algorithm wants the driver to re-tune or not.

Mauro Carvalho Chehab 9fe3301824 [media] ds3000: convert set_fontend to use DVBv5 parameters
Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.

Also, fill the supported delivery systems at dvb_frontend_ops
struct.

Mauro Carvalho Chehab bc9cd2736b [media] Rename set_frontend fops to set_frontend_legacy
Passing DVBv3 parameters to set_frontend is not fun, as the
core doesn't have any way to know if the driver is using the
v3 or v5 parameters. So, rename the callback and add a new
one to allow distinguish between a mixed v3/v5 paramenter call
from a pure v5 call.

After having all frontends to use the new way, the legacy
call can be removed.

Use kzalloc rather than the combination of kmalloc and memset.

The semantic patch that makes this change is as follows:

Fix a divide-by-zero error in ds3000's ds3000_read_snr(), when getting
a very low signal reading (dvbs2_signal_reading >= 1). This prevents
some nasty EIPs when running szap-s2 with a very low signal strength.
