Mauro Carvalho Chehab 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.

Mauro Carvalho Chehab 612ae142ac [media] xc4000: add module meta-tag with the firmware names
This meta-tag is used by some distros to help them package
the firmware and generate proper initrd images.

So, add the firmware names there.

Mauro Carvalho Chehab da7bfa2c5d [media] xc4000: Update firmware name
The firmware name at:
   http://www.kernellabs.com/firmware/xc4000/

Is different from the one at the Kernel. Update it
try first the new name, falling back to the previous one
if the new name can't be found.

Ezequiel Garcia 36628731ec [media] tuners/xc4000: Replace memcpy with struct assignment
This kind of memcpy() is error-prone. Its replacement with a struct
assignment is prefered because it's type-safe and much easier to read.
Found by coccinelle. Hand patched and reviewed.
Tested by compilation only.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier struct_name;
struct struct_name to;
struct struct_name from;
expression E;
@@
-memcpy(&(to), &(from), E);
+to = from;
// </smpl>

Mauro Carvalho Chehab ccae7af2bf [media] common: move media/common/tuners to media/tuners
Move the tuners one level up, as the "common" directory will be used
by drivers that are shared between more than one driver.
