🎀 reset_cdx_device(9) — Kernel API Manual 🎀

okay bestie, buckle up, because today we're looking at reset_cdx_device from the Kernel API Manual (section 9, yes, the kernel one 💅). It does exactly what it says on the tin: it resets a CDX device. That's the whole vibe. Iconic, lowkey, one job.

✨ NAME ✨

reset_cdx_device — Reset a CDX device

like… that's it. that's the function. she resets a CDX device and she does it well 🫶

🌸 SYNOPSIS 🌸

int reset_cdx_device (struct device *dev , void *data );

yes the spacing is a little feral, no we are not fixing it, it's literally exactly how it's written, periodt 💀

🦋 ARGUMENTS 🦋

  • dev — the CDX device. the main character of this whole operation. the one getting reset ✨
  • data — okay so this one is a little silly 🙈 it is always passed as NULL, and it is not used in this API at all. so why is it even here? because the device_for_each_child API expects the function you pass it to have this as an argument. so it's basically a plus-one that nobody talks to at the party. required, but not used. we've all been there 🎀

💖 RETURN 💖

  • -errno on failure 😭
  • 0 on success 🎉

like, she tells you how it went. communication queen 👑

🌈 SEE ALSO 🌈

go read those too, they're all in their little CDX friend group and honestly? the lore is real 🧚

ngl this one's short but she's important. don't skip the data argument even though it's NULL forever — the API said so, and we respect the API in this house 💅

and that's the whole page bestie!! this lil' icon lives at ./drivers/cdx, dated October 2026, and it goes by reset_cdx_device(9) — mwah, slay, see u in the next manpage 💜🍓
