dm_test_crtc...ne_no_stream(9)

🌸 NAME 🌸

dm_test_crtc_set_crc_source_none_no_stream — bestie, this is the Test valid source no-stream exit test, periodt. 💅 (also known as dm_test_crtc...ne_no_stream(9) in the Kernel API Manual, because the header had to truncate it and honestly? relatable.)

---

✨ SYNOPSIS ✨

void dm_test_crtc_set_crc_source_none_no_stream (struct kunit *test );

---

🎀 ARGUMENTS 🎀

• test — the KUnit test context. that's it, that's the whole vibe. it's the little passport this test carries around 🫶

---

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕ — this test verifies that a valid NONE request actually makes it inside the set-source body, reads the current CRC state, and then exits cleanly when the configuration gets deferred because no stream is attached. 💀

That's it! No stream, no problem, no drama — the request is valid, it just gets deferred, and the test is checking that everybody behaves. iconic behaviour fr fr. ✨
