find_volume(9)

💖 find_volume(9) — Kernel API Manual, but make it bestie-friendly 💖

okay so bestie, this is the find_volume(9) page from the Kernel API Manual, and it's literally about finding a volume-supported HW port by HW port number. It's giving tiny-but-iconic kernel helper energy, no cap. 💅✨

🎀 NAME 🎀

find_volume — find volume supported HW port by HW port number. 🫶

🌸 SYNOPSIS 🌸

struct uniphier_aio_sub * find_volume (struct uniphier_aio_chip *chip ,
int oport_hw );

🦋 ARGUMENTS 🦋

• chip — the AIO chip pointer. that's the chip bestie 💖
• oport_hw — HW port number, one of AUD_HW_XXXX. iykyk ✨

✨ DESCRIPTION ✨

Find AIO device from device list by HW port number. periodt. 🎀

Volume feature is available only in Output and PCM ports — and yes, that limitation comes from HW specifications. not me being limited by hardware 😭💀

🔥 RETURN 🔥

The pointer of AIO substream if successful, otherwise NULL on error. so if it slays, you get the pointer; if not, NULL. 🫶

okay bestie, that's the whole vibe. This page is from the source/version ./sound/soc/uniphier, dated October 2026, and it's the find_volume(9) manual page. bye, love you, read your kernel docs! 🦋💖🎀
