Staging: comedi: pcl816: update convert_src mask for AI cmdtest
The COMEDI_CMDTEST ioctl needs to clear unsupported bits in the struct comedi_cmd's convert_src and other *_src members. This needs fixing in the pcl816 driver's AI cmdtest. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
