💅 mucse_mbx_reset_hw(9) — the kernel API manual, but make it cute

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is mucse_mbx_reset_hw. yes that's a lot of letters. no we're not scared of it. let's go 🎀

✨ NAME ✨

mucse_mbx_reset_hw — posts a mbx req to reset hw 🫶

like, literally what it says on the tin. it slides a mailbox request over to the firmware and asks it, very politely, to reset the hardware.

---

🌸 SYNOPSIS 🌸

int mucse_mbx_reset_hw (struct mucse_hw *hw );

she takes one (1) argument and gives you back an int. that's it. that's the whole vibe check. ⭐

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 💖 this is the hardware struct you're handing over, and it's the thing that's gonna get reset, so like… treat it with respect pls.

---

🧚 DESCRIPTION 🧚

okay so here's the tea 🔥 — mucse_mbx_reset_hw posts a mbx req to firmware to reset hw. that's the entire job. it sends the request, and then we use mucse_fw_send_cmd_wait_resp to wait hw reset ok. periodt. 💅

like, the function itself isn't out here doing backflips — it's the messenger, and mucse_fw_send_cmd_wait_resp is the one standing there refreshing the page waiting for firmware to say "done ✨".

---

👑 RETURN 👑

• 0 on success 🎉 (slay)
• negative errno on failure 😭 (ngl, you're gonna want to check this one)
