Staging: sst: more dereferencing user pointers
This is another patch about making a copy of the data into kernel space
before using it. It is easy to trigger a kernel oops in the original
code. If you passed a NULL to SNDRV_SST_SET_TARGET_DEVICE then it
called BUG_ON(). And SNDRV_SST_DRIVER_INFO would let you write the
information to arbitrary memory locations which is a security violation.
