✨ devm_reset_control_get_exclusive — the Kernel API Manual ✨

okay so bestie, this is a page from the Kernel API Manual (yes, that manual, the one with the (9) section number, we love a numbered section) and it's about devm_reset_control_get_exclusive. it's giving "small function, big responsibilities" and honestly? iconic. let's get into it 💅

🎀 NAME 🎀

devm_reset_control_get_exclusive — resource managed reset_control_get_exclusive()

like, the managed version. the one that cleans up after itself. main character energy fr fr 🫶

✨ SYNOPSIS ✨

struct reset_control * devm_reset_control_get_exclusive (struct device
*dev , const char *id );

that's the whole signature and no, you cannot change it, no cap. write it exactly like that 😌

🦋 ARGUMENTS 🦋

  • dev — the device that's gonna get reset by the controller. it's the lil guy being poked 🫣
  • id — the reset line name. that's how you tell the controller which line you're talking about, iykyk

🌸 DESCRIPTION 🌸

so this is the Managed reset_control_get_exclusive.

here's the slay part: for reset controllers you got back from this function, reset_control_put is called automatically on driver detach. like, you literally don't have to do anything. automatic. the kernel handles it. obsessed 😭✨

and if you want more info, go read reset_control_get_exclusive — this one's basically that but with the devm cleanup glow-up 💖

🔥 real talk: the "managed" in the name is doing a lot of heavy lifting here. you're not manually calling reset_control_put yourself, that's the whole vibe of devm_*. it just happens on detach. periodt.

and now, the friend group. the whole extended family. every single one of them, bestie, we don't skip anyone 💀

that's 36 of them. thirty-six. we counted. we always count 🔢💜

and that's the whole page, bestie! 🌈 this beauty lives in the kernel source at ./include/linux and it's dated October 2026, which like… future vibes but make it documentation ⭐ slay, go reset some hardware responsibly 🎀💖
