msm_dp_audio_get(9)

💅 msm_dp_audio_get(9) — like, the kernel API manual one 🎀

okay bestie, so this is a page straight out of the kernel API manual, and it's about one lil function: msm_dp_audio_get. name says it all tbh — you're getting the DP audio thing. ✨

---

🌸 NAME 🌸

msm_dp_audio_get — and honestly? the original page leaves the description blank after the dash 🙈 so all the tea is down in DESCRIPTION. keep reading, i promise it's worth it.

---

🦋 SYNOPSIS 🦋

struct msm_dp_audio * msm_dp_audio_get (struct platform_device *pdev ,
       void __iomem *link_base );

like, you hand it two things and it hands you back a struct msm_dp_audio *. iconic behavior ngl. 👑

---

🎀 ARGUMENTS 🎀

• pdev — the caller's platform device instance. basically your device, the one doing the asking. 🫶
• link_base — a pointer to the msm_dp_link resource. that's the link base address, mwah. 💜

---

✨ DESCRIPTION ✨

so what does it do? it creates an instance of dp audio. that's the whole vibe. 🎵

and if things go sideways, it returns an error code. otherwise — when everything slays — you get back an instance of the newly created msm_dp_module. periodt. 💅

no cap tho: failure means you're getting an error code, not an instance. check your return value, bestie, don't just assume. 😭

• the kernel file ./drivers/gpu/drm/msm/dp/dp_audio.h — go read it, iykyk 📖
• struct msm_dp_audio(9)
• msm_dp_audio_put(9) — the one that gives it back, because what goes up must come down 🦋

and that's the whole page, bestie! 🫶 this lil gem lives at ./drivers/gpu/drm/msm/dp and the page itself is dated October 2026 — mark your calendars, mwah 💋🌈⭐
