media_set_bus_info(9)

💅 NAME 💅

okay so this whole page is about media_set_bus_info — it sets the bus_info field. that's the vibe, that's the whole job, she's a one-task icon ✨

this is the media_set_bus_info(9) page from the Kernel API Manual, btw 🎀

---

✨ SYNOPSIS ✨

void media_set_bus_info (char *bus_info , size_t bus_info_size , struct device *dev );

like, that's the whole signature bestie, no cap 🔥

---

🫶 ARGUMENTS 🫶

• bus_info — the variable where we write the bus info, and yes it's a char array 💖
• bus_info_size — the length of the bus_info (so she knows how much room she's got, very considerate of her tbh)
• dev — the related struct device 🌸

---

🦋 DESCRIPTION 🦋

so what she does is set the bus information based on dev. currently this is done for PCI and platform devices — that's the range, that's her lane, iykyk 💅

dev is required to be non-NULL for this to happen. like, actually required. no device, no bus info, that's the deal 🙈

⚠️ real talk though — this function is not meant to be called from drivers. so if you're out here writing a driver and thinking "ooh let me call this", no. not for you. she said not in this group chat 🫶
