💅 comedi_to_usb_interface(9) 💅

okay so this one is straight out of the Kernel API Manual, and it's all about pulling the USB interface that's attached to a COMEDI device. lowkey a little conversion moment, and it ate. 💖

✨ NAME ✨

comedi_to_usb_interface — return the USB interface attached to a COMEDI device. 🦋

🌸 SYNOPSIS 🌸

struct usb_interface * comedi_to_usb_interface (struct comedi_device
       *dev );

🎀 ARGUMENTS 🎀

• dev — a COMEDI device. that's the whole vibe check for this arg 💅

🧚 DESCRIPTION 🧚

assuming dev->hw_dev is non-NULL, it's assumed to be pointing to a struct device embedded in a struct usb_interface. that's it, that's the whole "trust the pointer" moment, no cap. ✨

heads up bestie: this is literally built on that assumption, so dev->hw_dev is the main character here. 👑

🔥 RETURN 🔥

• the attached USB interface, if dev->hw_dev is non-NULL. 🫶
• NULL, if dev->hw_dev is NULL. 😭
