Linux 4.7 or former have no validator of dimension information. This can causes an issue related to user-defined element set. For example, When calculated total members in multi-dimensional matrix is larger than actual capacity of snd_ctl_elem_value_t, processes to handle the element can cause buffer-over-run.
For backward portability of this userspace library, this commit adds a validator of dimension information. When userspace applications give invalid dimension information to APIs to add element set, they receive -EINVAL.
