Staging: sst: copy_from_user() changes

These patches fix some issues with using user space pointers in the sst ioctl. It's sort of a larger patch than I normally write and I don't have the hardware. I tried to be careful, but please test it. :)

There are more things left to patch but I wanted to send what I had so far.

regards,
dan carpenter

Sure, please give me a couple of days to see how this patch set works
