stm32_spi_can_poll(9)

💅 stm32_spi_can_poll — Kernel API Manual, bestie edition

okay so real talk, this one's from the Kernel API Manual — section 9, kernel devs only, no gatekeeping ✨

---

🌸 NAME 🌸

stm32_spi_can_poll — the little vibe check that tells you whether a poll-based transfer is the move or not 💅

---

✨ SYNOPSIS ✨

bool stm32_spi_can_poll (struct stm32_spi *spi );

---

🎀 ARGUMENTS 🎀

• spi — pointer to the spi controller data structure. yeah that's it, just the one, she's low maintenance 🫶

---

💖 DESCRIPTION 💖

Returns true if poll is more appropriate, and false otherwise. literally that's the whole thing, it's giving "short and iconic" 👑

(and yes, the original really does say "Returns true is poll is more appropriate" — typo and all, we keep it 💀 it's part of the lore now)
