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 Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Ronald Bultje <rbultje@ronald.bitfreak.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
