🌸 SYNOPSIS 🌸

int vpu_wdt_reg_handler (struct platform_device *pdev , void *priv ,

🦋 ARGUMENTS 🦋

• pdev — VPU platform device vpu_wdt_reset_func: the callback reset function.
• priv — the private data for reset function 💜
• priv — the private data for reset function 💜 yep, it shows up twice, bestie — keeping both exactly as listed.
• id — reset id 🆔
