✨ SYNOPSIS ✨

here's the signature, bestie — copy it exactly, don't freestyle:

void heci_reg_write (const struct issei_heci_hw *hw , unsigned long
offset , u32 value );

🎀 ARGUMENTS 🎀

• hw — the heci hardware structure. that's your device bestie.
• offset — offset from which to write the data. where we're writing, periodt.
• value — register value to write (u32). the actual payload, typed as a u32.
