🌸 sprd_mcdt_request_chan(9) 🌸

okay bestie, welcome to the Kernel API Manual ✨ — this one's a lil function called sprd_mcdt_request_chan, and no cap, it's the moment you go get yourself an MCDT channel. Let's get into it 💅

✨ NAME ✨

sprd_mcdt_request_chan — request one MCDT channel 🎀

Like, one. A single one. Not a whole pile. Okay? 🫶

🦋 SYNOPSIS 🦋

struct sprd_mcdt_chan * sprd_mcdt_request_chan (u8 channel , enum
       sprd_mcdt_channel_type type );

the way this returns a struct sprd_mcdt_chan * … main character energy honestly 👑

💖 ARGUMENTS 💖

  • channel — the channel id 🆔 (that's it, that's the whole vibe)
  • type — the channel type, and it can be either one ADC channel or a DAC channel, so pick your fighter 🎤

⭐ DESCRIPTION ⭐

Rreturn NULL if there's no available channel 😭

fr fr the manpage says "Rreturn" with two r's and I'm not about to fix it, that's between the kernel devs and god 🙈 — but the meaning is crystal: if nothing's free, you get NULL. no channel for you. vibe check failed 💀

🔥 SEE ALSO 🔥

Kernel file ./sound/soc/sprd/sprd-mcdt.c — and like, the whole MCDT squad honestly:

read them, love them, cite them in your commit message 💜

that's the whole page bestie, go forth and request your channel ✨
