void __iomem * devm_ioremap_uc (struct device *dev , resource_size_t
offset , resource_size_t size );

like, look at her. void __iomem * return type, three args, no notes 💖

🎀 ARGUMENTS 🎀

• dev — the generic device you're remapping the IO address for. she's the reason the "managed" part even works, so be nice to her 🫶
• offset — the resource address you wanna map. the where bestie 📍
• size — how big the map is. the how much ✨

💜 DESCRIPTION 💜

Managed ioremap_uc — that's the whole vibe 🔥

and here's the iconic part: the map is automatically unmapped on driver detach. no manual cleanup arc, no leak era, she just handles it 💀✨ devm said "i got u" and honestly? obsessed.
