regulator_set_drvdata(9)

okay bestie, we're cracking open regulator_set_drvdata(9) from the Kernel API Manual ✨ and it's giving “short king of a manpage” 👑. Let's get into it.

🎀 NAME 🎀

regulator_set_drvdata — set regulator driver data 💅

✨ SYNOPSIS ✨

void regulator_set_drvdata (struct regulator *regulator , void *data );

lowkey iconic that the whole synopsis fits in one line. The return type is void — no value comes back — and it takes a struct regulator * called regulator plus a void * called data. periodt 🫶

💖 ARGUMENTS 💖

• regulator — the struct regulator * named regulator. The page's description is literally “regulator,” and honestly? Minimalist queen, no notes 👑.
• data — the void * named data. Again, the page just says “data,” so we are not inventing extra lore 😌.

🦋 SEE ALSO 🦋

okay, the SEE ALSO section is huge and we are not skipping a single name, because every reference deserves its main character moment 🌈. The kernel file it points at is ./drivers/regulator/core.c, and here's the full roster:

mwah 💋 — the source/version corner says this page lives under ./drivers/regulator, dated October 2026, and the title on the tin is still regulator_set_drvdata(9) all the way to the end 🎀✨
