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.

56ac033725 [media] tuner-xc2028: Don't use dynamic static allocation
Dynamic static allocation is evil, as Kernel stack is too low, and
compilation complains about it on some archs:
	drivers/media/tuners/tuner-xc2028.c:651:1: warning: 'load_firmware' uses dynamic stack allocation [enabled by default]
Instead, let's enforce a limit for the buffer.
In the specific case of this driver, the maximum limit is 80, used only
on tm6000 driver. This limit is due to the size of the USB control URBs.
Ok, it would be theoretically possible to use a bigger size on PCI
devices, but the firmware load time is already good enough. Anyway,
if some usage requires more, it is just a matter of also increasing
the buffer size at load_firmware().

03c420010f [media] tuners/xc2028: 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>

Move the tuners one level up, as the "common" directory will be used
by drivers that are shared between more than one driver.
