🦋 SYNOPSIS 🦋

int devm_spi_offload_trigger_register (struct device *dev , struct
spi_offload_trigger_info *info );

like, look at her. two args, returns an int, no cap 🔥

---

🌸 ARGUMENTS 🌸

• dev — the device, and it's here for devm purposes — yep, that's the whole vibe, the devres magic is the point, iykyk ✨
• info — the provider-specific trigger info. provider-specific!! so it's your provider's little info blob, not a one-size-fits-all situation 🫶
