💅 drm_lspcon_get_mode(9) — the Kernel API Manual glow-up ✨

okay bestie, so this one lives in the Kernel API Manual and it's literally called drm_lspcon_get_mode — and no cap, the whole gig is: Get LSPCON's current mode of operation by reading offset (0x80, 0x41) 🎀

That's it. That's the vibe. We're reading a couple of little register offsets and finding out what headspace your LSPCON is in rn. 🦋

✨ SYNOPSIS ✨

int drm_lspcon_get_mode (const struct drm_device *dev , struct
i2c_adapter *adapter , enum drm_lspcon_mode *mode );

look at her go 😭 three args, one int return, absolutely iconic behaviour.

🌸 ARGUMENTS 🌸

  • dev — the drm_device to use, aka the main character of this whole operation 👑
  • adapter — the I2C-over-aux adapter, the little messenger that carries the gossip 🧚
  • mode — output variable for the current lspcon mode of operation; this is where the answer gets dropped off 💖

⭐ RETURN ⭐

  • 0 on success — and when it succeeds it sets the current_mode value to the appropriate mode 🫶
  • -error on failure — yes, negative error, we're in our flop era and the call did not slay 💀
fr fr: check that return value. 0 = we ate. anything else = we did not eat. 🙈
