spi_res_release(9)

💅 spi_res_release(9) — the tea ☕

okay so bestie, buckle up, this one's from the Kernel API Manual and it's literally called spi_res_release 🎀 — aka release all SPI resources for this message. That's the whole plot, no cap. It's giving cleanup arc, main character energy, and honestly? obsessed.

---

✨ NAME ✨

spi_res_release — release all SPI resources for this message 🧹💖

---

🌸 SYNOPSIS 🌸

void spi_res_release (struct spi_controller *ctlr , struct spi_message *message );

note the void up front bestie — this one returns nothing, it just does the thing and dips 💅

---

🦋 ARGUMENTS 🦋

• ctlr — the spi_controller 🎛️ like, the controller in question. the boss of the bus.
• message — the spi_message ✉️ the message whose resources we're yeeting back into the void.

fr fr: both of these are required, the synopsis says so, don't come for me 🙈
