regmap_exit(9)

💖 regmap_exit(9) 💖

okay so bestie, this is a page from the Kernel API Manual (yes, the kernel has a manual, she's fancy like that) and it's all about regmap_exit — the little cleanup queen that frees a previously allocated register map. Think of it as the "and we're done here, close the tab, log off, hydrate" of regmap land. ✨

🌸 SYNOPSIS 🌸

void regmap_exit (struct regmap *map );

that's it. that's the whole signature. void in, void out — she takes no prisoners and returns nothing, which is honestly such main character energy. 🎀

🦋 ARGUMENTS 🦋

• map — the register map you wanna operate on. like, the actual struct regmap * you're sending off into the sunset. hand her over, bestie. 🫶

lowkey important: this is the freeing function, so map is the thing that's about to stop existing. just saying. 💀

like, forty-one whole entries. she's an icon, she's a legend, and she is the moment. 👑

and that's the whole page, bestie 💖✨

this cutie lives under ./drivers/base/regmap, dated October 2026, and honestly? iconic of her. go free that register map responsibly. 🧚‍♀️🌷
