okay so welcome to heci_fwcsr_read(9) from the Kernel API Manual, bestie — this one is lowkey iconic 💅✨

🌸 NAME 🌸

heci_fwcsr_read — reads 32bit data from the FW CSR. That's the whole vibe, no cap; it's a tiny helper with main character energy and we're obsessed 🫶

✨ SYNOPSIS ✨

the signature is literally this, no notes:

u32 heci_fwcsr_read (const struct issei_device *idev );

🎀 ARGUMENTS 🎀

• idev — the device structure. That's the argument, bestie; it's giving "pass me the device struct" energy 🎀

💖 RETURN 💖

It hands back the FW_CSR_HA register value as a u32, periodt 💖
