💅 spi_offload_trigger_validate(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, this is that spi_offload_trigger_validate page, and no, we are not skipping any of it 🫶

---

✨ NAME ✨

spi_offload_trigger_validate</p> — it validates the trigger you asked for. literally its whole job 💅

---

🌸 SYNOPSIS 🌸

int spi_offload_trigger_validate (struct spi_offload_trigger *trigger ,
struct spi_offload_trigger_config *config );

---

🎀 ARGUMENTS 🎀

• trigger — the offload trigger instance, the main character of this whole function ngl 👑
• config — the trigger config you want validated, hand it over and let the kernel vibe check it 🦋

---

💖 DESCRIPTION 💖

so on success, config may be modified to reflect what the hardware can actually do. not a typo, not a glitch — the function is allowed to rewrite your config. iconic behavior honestly ✨

for example, the frequency of a periodic trigger may be adjusted to the nearest supported value. like, the hardware is politely nudging you toward something it can actually pull off 🧚

heads up bestie — because config can get tweaked on you, callers will likely need to do additional validation of the modified trigger parameters. do not just trust it and walk away 😭

---

⭐ RETURN ⭐

• 0 on success 💚
• a negative error code on failure 💀
