fwctl_alloc_device(9)

🌈 NAME 🌈

fwctl_alloc_device(9) — welcome to the Kernel API Manual, bestie. This one is literally Allocate a fwctl. No cap, that's the whole name vibe. 💅

✨ SYNOPSIS ✨

fwctl_alloc_device (parent , ops , drv_struct , member );

🎀 ARGUMENTS 🎀

• parent — physical device that provides the FW interface 🫶
• ops — driver ops to register ✨
• drv_struct — this argument is listed here, but the source page doesn't give it a separate one-liner 🙈
• member — name of the struct fwctl_device in drv_struct 🎀

🌸 DESCRIPTION 🌸

Okay so this allocates and initializes the fwctl_device embedded in the drv_struct. Iconic. 👑

Upon success the pointer must be freed via fwctl_put — yes, must, bestie, don't leave it hanging 😭💅.

Returns a 'drv_struct on success, NULL on error. That's the whole returns situation, fr fr. 🌈
