cec_notifier_set_phys_addr(9)

🎀 cec_notifier_set_phys_addr 🎀

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function that lives in your kernel headers and it is so lowkey but honestly kind of a baddie. let's get into it 💅

---

🌸 NAME 🌸

cec_notifier_set_phys_addr — set a new physical address, that's it, that's the whole vibe 🫶

---

✨ SYNOPSIS ✨

void cec_notifier_set_phys_addr (struct cec_notifier *n , u16 pa );

like look at her. void return, two args, no drama, no cap 🔥

---

🦋 ARGUMENTS 🦋

• n — the CEC notifier 💖 like, the actual notifier struct you're poking at. it's a struct cec_notifier *.
• pa — the CEC physical address, which is a u16. this is the new address you wanna set. that's the whole point bestie 🎯

---

🌈 DESCRIPTION 🌈

so what does it do?? it sets a new CEC physical address ✨ that's the assignment, she delivers.

and here's the part where the function is extremely chill: it does nothing if n == NULL 😌 no crash, no explosion, no "not me getting a segfault in production" moment — just silence. if n is NULL, she simply does not participate 💀

fr fr, that NULL check is the entire safety net here. n == NULL → nothing happens. iconic behaviour honestly.
