πŸ’… comedi_usb_auto_unconfig

okay so bestie, welcome to the Kernel API Manual ✨ β€” this one's a little kernel helper called comedi_usb_auto_unconfig, and honestly it's giving cleanup crew energy πŸ§ΉπŸ’–


🌸 NAME 🌸

comedi_usb_auto_unconfig β€” unconfigure/disconnect a USB COMEDI device 🫢


✨ SYNOPSIS ✨

void comedi_usb_auto_unconfig (struct usb_interface *intf );

literally just one lil function, no cap πŸŽ€


πŸ¦‹ ARGUMENTS πŸ¦‹

  • intf β€” the USB interface. that's it, that's the whole argument list πŸ’…

πŸ‘‘ DESCRIPTION πŸ‘‘

so like, the vibe here is: this gets typically called from the usb_driver (*disconnect) function πŸ”Œβœ¨ β€” you know, when the device is peacing out.

What it does: it auto-unconfigures a COMEDI device that's attached to this USB interface, and it uses a pointer to the struct device embedded in *intf as the hardware device. cute, right? πŸŽ€

and while the COMEDI device is being unconfigured, the COMEDI driver's "detach" handler gets called. so it's not just a shrug-and-leave, there's an actual handler doing its main character moment πŸ’…πŸ”₯

⚠️ okay important note bestie: the COMEDI device may have already been unconfigured using the COMEDI_DEVCONFIG ioctl 😭 in that case, this attempt to unconfigure it again should be ignored. don't double-unconfigure, it's not the vibe πŸ™ˆ
