staging: comedi: adl_pci7x3x: fix pointer-to-int-cast warning
PATCH 1/1 staging: comedi: adl_pci7x3x: fix pointer-to-int-cast warning
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.
