staging: comedi: comedi_fops: rename the __user *cmd param in do_cmd_ioctl
This parameter is actually the unsigned long arg passed in the ioctl. comedi_unlocked_ioctl() casts it as a (struct comedi_cmd __user *) when calling do_cmd_ioctl(). Rename the variable to keep this clear. Signed-off-by:H Hartley Sweeten <hsweeten@visionengravers.com> Cc: Ian Abbott <abbotti@mev.co.uk> Acked-by:
