[media] cx25840: Fix compilation for i386 architecture
WARNING: "__udivdi3" [/home/v4l/new_build/v4l/cx25840.ko] undefined! 64 bits division need to call do_div & friends, in order to allow it to compile with 32 bits kernels Cc: Steven Toth <stoth@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
