devm_sdca_irq_allocate(9)

💅 devm_sdca_irq_allocate ✨

okay bestie, welcome to the Kernel API Manual — this one's short and sweet and honestly kind of a vibe 🎀

---

🦋 NAME 🦋

devm_sdca_irq_allocate — literally just allocates an SDCA interrupt structure for a device. that's the whole job. no cap 💖

---

✨ SYNOPSIS ✨

struct sdca_interrupt_info * devm_sdca_irq_allocate (struct device *sdev
, struct regmap *regmap , int irq );

look at her. three args, one pointer back, iconic behavior only 👑

---

🌸 ARGUMENTS 🌸

• sdev — the device pointer, and yes she's the one everything gets allocated against (devm energy — the cleanup is not your problem, bestie 🫶).
• regmap — the regmap used to poke at the SDCA IRQ registers. this is the access route, treat her right.
• irq — the interrupt number. the actual number. the irq itself. fr fr 💀

---

💜 DESCRIPTION 💜

so the way this works: typically you'd call this from the top level driver for the whole SDCA device. why? because only a single instance is required across all Functions on the device. one. uno. that's the tea ☕ — don't be out here allocating one per Function, that's not the move 🙈

---

🌈 RETURN 🌈

a pointer to the allocated sdca_interrupt_info struct — or an error code 😭 (so like, always check, bestie. always check.)
