Jean Delvare 85b9b8a444 V4L/DVB (8499): zr36067: Rework device memory allocation
Allocate zoran devices dynamically. Currently, the zr36067 driver
stores the device structures in a global array, with room for 4
devices. This makes the bss section very large (90 kB!), and given
that most users, I suspect, have only one zoran device, this is a
waste of kernel memory. Allocating the memory dynamically lets us use
only the amount of memory we need.

Before:
   text    data     bss     dec     hex filename
  64754    9230   90224  164208   28170 drivers/media/video/zr36067.o

After:
   text    data     bss     dec     hex filename
  64866    9230     112   74208   121e0 drivers/media/video/zr36067.o
