💖 snd_power_sync_ref(9) 💖

okay so bestie, welcome to the Kernel API Manual page for snd_power_sync_ref(9). It’s giving tiny-but-important sync-helper energy, and we’re gonna get through it together 🫶

🌸 NAME 🌸

snd_power_sync_ref — wait until the card power_ref is freed ✨

🦋 SYNOPSIS 🦋

void snd_power_sync_ref (struct snd_card *card );

🎀 ARGUMENTS 🎀

• card — sound card object. that’s the thing you’re passing in, bestie 💅

💜 DESCRIPTION 💜

This function is used to synchronize with the pending power_ref being released.

Lowkey that’s the whole vibe: snd_power_sync_ref() waits until the card’s power_ref is freed, and it’s there to sync up with a pending power_ref that’s getting released. no extra plot twists, just that synchronization moment ⭐
