[igt-dev] [PATCH i-g-t 2/5] tests/kms_hdmi_inject: Provide igt_descriptions

[Arkadiusz Hiler <arkadiusz.hiler@intel.com>]

This test is quite simple which makes it perfect for the first real
world example of igt_describe usage.

- * Currently, this can be used to test:
- *
- * - 4K modes exposed via KMS
- * - Audio capabilities of the monitor exposed via ALSA. EDID-Like Data (ELD)
- *   entries in /proc/asound are verified.
- *
- * Injection is performed on a disconnected connector.
