usx2y: don't bother with access_ok() in ->dsp_load()
memdup_user() checks it, so the only effect would be failing with -EINVAL instead of -EFAULT in case when access_ok() is false. However, the caller has already checked access_ok() itself (and would have buggered off with -EFAULT), so the check is completely pointless. Removing it both simplifies the only instance of ->dsp_load() and allows to get rid of the check in caller - its sole effect used to be in preventing a bogus error value from access_ok() in the instance. Let memdup_user() do the right thing instead... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
