💅 dm_mst_test...i2c_read_mot(9) — Kernel API Manual ✨

Ok bestie, welcome to the dm_mst_test...i2c_read_mot(9) page. This is the Kernel API Manual, and we're about to decode one tiny test helper together. Slay. 🫶

🎀 NAME 🎀

dm_mst_test_fill_payload_flags_i2c_read_mot — I2C read with MOT request decode. That's the vibe: one test helper, one very specific decode job. 💅

✨ SYNOPSIS ✨

void dm_mst_test_fill_payload_flags_i2c_read_mot (struct kunit *test );

Copy-paste that exactly, bestie; don't let autocorrect touch it. 😭

🧚 ARGUMENTS 🧚

• test — KUnit test context. It's the little context bag the test hands over. That's the whole argument list, periodt. 🎀

🌸 DESCRIPTION 🌸

Okay so here's the flag tea: DP_AUX_I2C_READ sets i2c_over_aux and clears write; DP_AUX_I2C_MOT sets mot. That's literally the decode behavior this helper is testing. No cap. ✨
