rio_match_bus(9)

✨ rio_match_bus(9) ✨

Kernel API Manual bestie incoming — this is rio_match_bus(9), and its whole thing is telling you if a RIO device structure has a matching RIO driver device id structure. 💅

🌸 SYNOPSIS 🌸

int rio_match_bus (struct device *dev , const struct device_driver *drv );

🎀 ARGUMENTS 🎀

• dev — the standard device structure to match against. That's the device bestie under interrogation. 🕵️‍♀️
• drv — the standard driver structure containing the ids to match against. It's bringing the list of supported devices to the group chat. 📋

💖 DESCRIPTION 💖

Okay so picture this: a driver uses this to check whether a RIO device that's present in the system is in its list of supported devices. That's literally the whole job. If there's a matching struct rio_device_id, it returns 1; if there's no match, it returns 0. Periodt. ✨
