ks8851_lock(9)

💅 ks8851_lock — a Kernel API Manual moment (that's ks8851_lock(9) babe)

okay so bestie, gather round, because this one is short and sweet and honestly iconic for it. We're in the ks8851_lock(9) page, and it is exactly what it says on the tin: it locks the chip's register access. That's the whole plot. No plot twists. Periodt.

✨ NAME ✨

ks8851_lock — the register access lock, aka the bouncer at the door of the chip's registers 🎀

✨ SYNOPSIS ✨

void ks8851_lock (struct ks8851_net *ks );

✨ ARGUMENTS ✨

• ks — the chip state 🦋 (your struct ks8851_net *, the main character of this whole function)

✨ DESCRIPTION ✨

Claim the chip register access lock. That's it. That's the vibe.

Like, you call this when you wanna get in on those registers and you do not want somebody else stomping through at the same time — so you claim the lock first, no cap 🔥

Lowkey the entire job of this function is one line of description in the original and I am respecting that. It claims. You access. Slay.
