ALSA: Fix a const pointer usage warning in the Digigram VX soundcard driver
Fix a const pointer usage warning in the Digigram VX soundcard driver. A const pointer is being passed to copy_from_user() to load the firmware into. This is okay in this case because the function has allocated the firmware struct itself, but the const qualifier is part of the firmware struct - so the patch casts the const away.
