cdx_bus_add(9)

✨ NAME ✨

okay bestie, this is cdx_bus_add(9) from the Kernel API Manual — and it is lowkey iconic for one very specific job. cdx_bus_add adds a CDX bus. Fr fr, it adds a bus on the CDX bus subsystem, creates a CDX device for the corresponding bus, and also registers an associated Linux generic device. periodt 💅

🌸 SYNOPSIS 🌸

the signature is giving exactly this, character for character:

struct device * cdx_bus_add (struct cdx_controller *cdx , u8 bus_num );

🎀 ARGUMENTS 🎀

• cdx — the associated CDX controller. That's the plug, bestie 🫶
• bus_num — the original one-liner is literally -- undescribed --, so no cap, I'm not inventing a description. That's the actual text 🙈

💖 RETURN 💖

On success: the associated Linux generic device pointer. On failure: NULL. That's the whole return vibe check, bestie 👑✨
