platform_device_del(9)

📦 version 7.3.1, in nixpkgs unstable

💅 platform_device_del — like, the Kernel API Manual one, bestie

okay so real talk, this is platform_device_del from the Kernel API Manual and it's honestly giving "cleanup era" in the best way. sit down, grab a lil snack, we're gonna get into it 🍓

✨ NAME ✨

platform_device_del — remove a platform-level device. that's it, that's the whole vibe check 🎀

🦋 SYNOPSIS 🦋

void platform_device_del (struct platform_device *pdev );

like yes, that's the whole signature, no cap. void in, void out, the function does its thing and does not return anything to you. periodt ✨

🌸 ARGUMENTS 🌸

  • pdev — the platform device we're removing. that's your main character right there, the one getting yeeted 👋 it's a struct platform_device *, k?

💖 DESCRIPTION 💖

okay so listen up because this part actually matters 🔥

lowkey this function doesn't just remove the device — it also releases all memory- and port-based resources owned by the device, and those live in dev->resource. so like, all of it, gone, freed, bye 🙈 so don't be out here assuming your resources are still yours afterwards, because they are so not.

🚨 and here's the big one, bestie: this function must _only_ be externally called in error cases. that's _only_ with the underscores, which is manpage-speak for "I am not joking." all other usage is a bug. not a quirky little bug, not a "haha oops" bug — a bug bug. 💀 so if you're calling this on the happy path, no you're not, go fix that fr fr.

🫶 SEE ALSO 🫶
