Subject: ctl: support dimension test for user-defined element set
X-Git-Tag: v1.1.2~99
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=ea7bc7f91a4053b11a3c266a3c547b9fb3de3266;p=alsa-lib.git

ctl: support dimension test for user-defined element set

In former commits, APIs to add an element set are extended to support extra
fields to information structure. Currently, the fields are mainly used to
describe dimension level.

This commit adds tests to check the dimension level.
