of_fpga_mgr_get(9)

💅 of_fpga_mgr_get(9) — like, the kernel API manual, bestie 🎀

okay so real talk, this is a page from the Kernel API Manual, and it's about one very specific little function that gets you a reference to an FPGA manager. it's short, it's sweet, it's giving "small but mighty" energy. let's get into it ✨

---

🌸 NAME 🌸

of_fpga_mgr_get — literally: given a device node, get a reference to an fpga mgr. that's it. that's the whole vibe. 🫶

---

🦋 SYNOPSIS 🦋

struct fpga_manager * of_fpga_mgr_get (struct device_node *node );

yes bestie, it returns a struct fpga_manager * and it takes exactly one argument. no cap, that's the entire signature 💅

---

🍓 ARGUMENTS 🍓

• node — the device node. that's it, that's the whole description. it's a device node. iconic minimalism honestly 👑

---

🔥 RETURN 🔥

it hands you back an fpga manager struct, or an IS_ERR condition containing an error code. so like… vibe check the return value before you go dereferencing it, mkay? 😭 if it's an error pointer, it's an error pointer. do not pass go, do not collect $200.

tiny reminder that this whole page lives under ./drivers/fpga and it's dated October 2026, and the page itself is of_fpga_mgr_get(9) — and yeah, that's genuinely it, that's the whole man page. short king behavior 👑✨💜
