platform_de...dd_resources(9)

💅 okay so it's platform_device_add_resources o'clock 💅

bestie, welcome to the Kernel API Manual — yes, that one — for platform_device_add_resources. it's giving “I copy your resources so future-you doesn't get left on read.” let's go. 🫶

🌸 NAME 🌸

platform_device_add_resources — add resources to a platform device

✨ SYNOPSIS ✨

here's the signature, exactly, no edits bestie:

int platform_device_add_resources (struct platform_device *pdev , const
       struct resource *res , unsigned int num );

🎀 ARGUMENTS 🎀

okay so these are the three things you're feeding it:

• pdev — the platform device allocated by platform_device_alloc that you're adding resources to. yes, that one. 👑
• res — the set of resources that needs to be allocated for the device. it's giving “here's the resource bundle.” 🎁
• num — the number of resources. literally the count. 🔢

💖 DESCRIPTION 💖

this function adds a copy of the resources to the platform device. not a “trust me bro” alias situation — a copy, no cap. 💅

and the memory associated with the resources will be freed when the platform device is released. so the cleanup is tied to the device release, periodt. 🧚
