mipi_dsi_dcs_nop(9)

💅 mipi_dsi_dcs_nop(9) — a Kernel API Manual moment

okay so bestie, welcome to the mipi_dsi_dcs_nop(9) page ✨ this is straight out of the Linux Kernel API Manual, and it's a whole mood: tiny function, big "we don't really use this anymore" energy.

---

🌸 NAME 🌸

mipi_dsi_dcs_nop — it sends a DCS nop packet. that's it. that's the whole job 🎀

---

🦋 SYNOPSIS 🦋

int mipi_dsi_dcs_nop (struct mipi_dsi_device *dsi );

---

💖 ARGUMENTS 💖

• dsi — your DSI peripheral device. the whole entire point of the call, honestly 🫶

---

✨ DESCRIPTION ✨

so here's the tea, and I need you to hear me on this one: this function is deprecated 😭

like, don't be out here writing new code with mipi_dsi_dcs_nop. the assignment has changed. please use mipi_dsi_dcs_nop_multi instead — that's the main character now 👑

ngl "deprecated" is not a vibe check you want to fail, so update your callers. fr fr.

---

🔥 RETURN 🔥

• 0 if it slayed (success)
• a negative error code if it did not (failure) 💀
