__subdev_set_power(9)

💅 __subdev_set_power(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for __subdev_set_power — it's giving “flip the power on one single subdev,” and we're keeping every deet. ✨

🎀 NAME 🎀

__subdev_set_power — changes the power state of one single subdev. one subdev, power state, handled. periodt. 💖

🌸 SYNOPSIS 🌸

int __subdev_set_power (struct v4l2_subdev *sd , int on );

🦋 ARGUMENTS 🦋

• sd — the subdevice whose power state you're changing. like, the main character subdev. 👑
• on — 1 to enable power or 0 to disable. binary bestie behavior, fr fr. ⚡

✨ DESCRIPTION ✨

It returns the result of the s_power subdev operation — or -ENXIO if the sd argument is NULL. NULL gets you -ENXIO, okay? 🫶

And if the subdevice does not implement s_power, it returns 0. so yes, no s_power equals a chill 0, no cap. 💅
