This driver uses the void *private variable in the comedi_subdevice
to pass the offset needed to read/write the appropriate register to
get/set the channels for the subdevice.
The adl_pci7x3x_do_insn_bits() and adl_pci7x3x_di_insn_bits() functions
were retrieving this offset by casting the s->private value as an
unsigned int. On 64-bit builds this results in a warning:
warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
Fix these warnings by casting the void * to an unsigned long.
