💅 sdca_ump_set_owner_device(9) — Kernel API Manual energy

okay so bestie, we're in the kernel API manual, and this lil function is literally the hand-back move. its whole job? give a UMP buffer's ownership back to the device. that's it. that's the vibe. 🫶

✨ NAME ✨

🌸 SYNOPSIS 🌸

int sdca_ump_set_owner_device (struct device *dev , struct regmap *function_regmap , struct sdca_function_data *function , struct sdca_entity *entity , struct sdca_control *control );

🎀 ARGUMENTS 🎀

five args, no cap, here's the lineup:

• dev — Pointer to the struct device used for error messages. it's giving "the one who does the yelling when things go wrong" 💀
• function_regmap — Pointer to the regmap for the SDCA Function. the map, the blueprint, the whole itinerary ✨
• function — Pointer to the Function information. yes, it's called function inside function-adjacent code, we don't make the rules 🌀
• entity — Pointer to the SDCA Entity. main character of this particular operation 💅
• control — Pointer to the SDCA Control for the UMP Owner. this is the one holding the "owner" receipts 🧾

⭐ RETURN ⭐

Returns zero on success, and a negative error code on failure. so like — 0 is the slay, anything negative is the "we don't talk about it" 😭

go look at the kernel file ./sound/soc/sdca/sdca_ump.c and also these icons:

• sdca_ump_get_owner_host(9)
• sdca_ump_read_message(9)
• sdca_ump_write_message(9)

ngl the owner flips both ways — sdca_ump_get_owner_host(9) is the other direction of this whole situationship 🔁
