💅 cdns3_clear_register_bit — like, the NAME section, bestie

okay so this is a page straight out of the Kernel API Manual and the star of the show is cdns3_clear_register_bit (9) ✨ she's a tiny little function, but she's important, and honestly? she ate.

short version: she clears a bit in a given register. that's it. that's the whole gig. no cap. 🎀

✨ SYNOPSIS ✨

void cdns3_clear_register_bit (void __iomem *ptr , u32 mask );

look at her go. two args, no return value, zero drama. 🦋

🫶 ARGUMENTS 🫶

  • ptr — the address of the device controller register that's gonna get read and changed. think of it as the address of the vibe you're about to edit 💅
  • mask — the bits requested to clar. yes, the manpage literally says clar 😭 iconic typo, we're keeping her, she's part of the lore. anyway: these are the bits you want cleared.
ngl if you're passing garbage in ptr that's on you — this page only tells you what it does, not how to be careful about it 🙈
