💖 NAME 💖

okay so welcome to __dev_pm_qos_flags(9), straight outta the Kernel API Manual — this is the page for checking PM QoS flags for a given device. periodt. 💅

✨ SYNOPSIS ✨

enum pm_qos_flags_status __dev_pm_qos_flags (struct device *dev , s32 mask );

🎀 ARGUMENTS 🎀

• dev — the Device to check the PM QoS flags for. like, this is the device we're looking at, bestie.
• mask — the flags to check against. that's the vibe check right there.

🦋 DESCRIPTION 🦋

okay so real talk: This routine must be called with dev->power.lock held. no cap, that's the whole description and it's kinda the most important part. don't skip the lock, bestie, i'm begging. 😭
