✨ idpf_ptp_init(9) ✨

okay so bestie, we're in the Kernel API Manual today and the main character is idpf_ptp_init 💅 this one's all about getting your PTP hardware clock situation set up — let's go 🫶

🌸 SYNOPSIS 🌸

int idpf_ptp_init (struct idpf_adapter *adapter );

🎀 ARGUMENTS 🎀

• adapter — the driver's own lil private structure, iykyk 👑

🦋 DESCRIPTION 🦋

so what it does is set up the device so it can interact with the PTP hardware clock for all functions, no cap ✨ and like, the function is gonna allocate and register a ptp_clock</> with the PTP_1588_CLOCK infrastructure — periodt, that's the whole vibe 💖

💀 RETURN 💀

• 0 on success 🎉
• -errno otherwise 😭
