acpi_nhlt_tb_find_endpoint(9) ✨💖

okay bestie, welcome to the Kernel API Manual page for acpi_nhlt_tb_find_endpoint — it’s literally giving “search a NHLT table for an endpoint” energy, and we’re gonna get you comfy with it 🫶

🌸 NAME 🌸

acpi_nhlt_tb_find_endpoint — Search a NHLT table for an endpoint.

---

✨ SYNOPSIS ✨

struct acpi_nhlt_endpoint * acpi_nhlt_tb_find_endpoint (const struct
acpi_table_nhlt *tb , int link_type , int dev_type , int dir , int
bus_id );

---

🎀 ARGUMENTS 🎀

• tb — the table to search. yes, that’s the one we’re snooping through 👀
• link_type — the hardware link type, e.g.: PDM or SSP.
• dev_type — the device type.
• dir — stream direction.
• bus_id — the ID of virtual bus hosting the endpoint.

---

🦋 DESCRIPTION 🦋

Either of link_type, dev_type, dir or bus_id may be set to a negative value to ignore the parameter during the search.

so if you’re not trying to filter on one of those, a negative value is your “not today, bestie” signal 🙈✨

---

💅 RETURN 💅

A pointer to endpoint matching the criteria, NULL if not found or an ERR_PTR otherwise.
