💅 fimc_pipeline_s_power(9) — Kernel API Manual 💅

💖 NAME 💖

fimc_pipeline_s_power — change power state of all pipeline subdevs. That's the whole assignment, bestie. 💖

🦋 SYNOPSIS 🦋

int fimc_pipeline_s_power (struct fimc_pipeline *p , bool on );

🎀 ARGUMENTS 🎀

• p — the fimc device that's terminating the pipeline. That's the main character here. 👑
• on — true to power on, false to power off. Simple as that, no cap. 💡

🌸 DESCRIPTION 🌸

Okay so, this is the function that changes the power state of all the pipeline subdevs. But the one thing you absolutely cannot skip: it needs to be called with the graph mutex held. Like, held-held. Not "probably", not "if you feel like it" — held. 💀

⚠️ Bestie, listen: graph mutex held when you call this. That's the whole vibe check. Don't skip it. 🙈
