sdca_ump_get_owner_host(9)

💅 sdca_ump_get_owner_host — the vibe check for UMP buffer ownership

okay so bestie, welcome to the Kernel API Manual ✨ this one lives in section 9 and it's basically a tiny little detective: it checks whether a UMP buffer is owned by the host. that's it, that's the whole personality 🎀

---

🦋 NAME

sdca_ump_get_owner_host — check a UMP buffer is owned by the host 👑

---

✨ SYNOPSIS

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

five arguments, one int, zero drama (hopefully) 💖

---

🌸 ARGUMENTS

• dev — pointer to the struct device, ngl this one is literally just here so error messages have somewhere to come from 😭 it's the messenger, not the main character.
• function_regmap — pointer to the regmap for the SDCA Function. yes, the whole thing. regmap girlies rise 🫶
• function — pointer to the Function information ✨
• entity — pointer to the SDCA Entity 🦋
• control — pointer to the SDCA Control for the UMP Owner 👑 like, the actual owner field we're checking.

lowkey every single one of these is a pointer, so please don't hand it nonsense, i'm begging 🙈

---

⭐ RETURN

Returns zero on success, and a negative error code on failure. that's the whole deal — 0 means slay, anything negative means something went sideways 💀
