✨ NAME ✨

  • device_for_each_child — device child iterator. periodt 💅

🦋 SYNOPSIS 🦋

int device_for_each_child (struct device *parent , void *data ,
       device_iter_t fn );

🎀 ARGUMENTS 🎀

  • parent — parent struct device. iconic.
  • data — data for the callback.
  • fn — function to be called for each device.

🌸 DESCRIPTION 🌸

Iterate over parent's child devices, and call fn for each, passing it data. no cap 🧚

We check the return of fn each time. If it returns anything other than 0, we break out and return that value. that's the whole vibe check 💖
