✨ mmc_regulator_disable_vqmmc(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's called mmc_regulator_disable_vqmmc(9) and it's literally the "turn the VQMMC regulator off for a host" girlie. short page, big vibes, let's go 🎀

🌸 NAME 🌸

mmc_regulator_disable_vqmmc — disable VQMMC regulator for a host 💅

🦋 SYNOPSIS 🦋

void mmc_regulator_disable_vqmmc (struct mmc_host *mmc );

that's it. that's the whole signature. no return value, no drama, she's void and she knows it 😌

🎀 ARGUMENTS 🎀

  • mmc — the host to regulate 🫶 like, this is the struct mmc_host * you're handing over so the function knows which host's regulator situation we're talking about. main character pointer energy.

💜 DESCRIPTION 💜

okay so first things first, and ngl this is a lil iconic: the page says it returns 0 or errno 😭 which is a whole mood given the signature up there is void — but that's what the doc says, so I'm telling you what the doc says, periodt. no notes, no corrections, I don't make the rules.

what it actually does: it disables the regulator for vqmmc ✨ that's the whole job, she's a one-task legend.

and the important part — the way that it does it: it keeps track of the enable status 👑 so that calls to regulator_enable/disable stay balanced. like, it's the friend who remembers who already paid for the iced coffee so nobody double-charges. if you enable and disable willy-nilly you get unbalanced calls, and this little bookkeeping is what prevents that mess. lowkey the most responsible member of the group chat 🧚

no cap — the balancing thing is the whole point here. the disable only makes sense in a world where the enable side got counted too.
