__media_device_usb_init(9)

💅 NAME 💅

okay so this is __media_device_usb_init(9) from the Kernel API Manual, and its whole thing is to create and initialize a struct &media_device from a PCI device. Yes, the NAME line says PCI — I'm just the messenger, bestie. 💀

✨ SYNOPSIS ✨

void __media_device_usb_init (struct media_device *mdev , struct
       usb_device *udev , const char *board_name , const char *driver_name );

🎀 ARGUMENTS 🎀

here's the tea on every single argument, no skips:

• mdev — pointer to struct media_device. this is the media device getting its glow-up.
• udev — pointer to struct usb_device. the USB device in question, slay.
• board_name — media device name. If NULL, the routine will use the usb product name, if available. so if you leave it blank, it'll try to snag the product name for you 🫶
• driver_name — name of the driver. if NULL, the routine will use the name given by udev->dev->driver->name, with is usually the wrong thing to do. yeah, that fallback is giving "trust me bro" 😭

🌸 DESCRIPTION 🌸

NOTE: It is better to call media_device_usb_init instead, as such macro fills driver_name with KBUILD_MODNAME.

like, the page itself is telling you to use the macro wrapper, okay? The NOTE is right there, bestie — don't make it weird. 🎀
