ufshcd_rmwl(9)

💅 NAME 💅

okay so this is ufshcd_rmwl(9) from the Kernel API Manual, and it performs a read/modify/write for a controller register. That's the whole assignment, bestie — read, modify, write, slay. 💖

✨ SYNOPSIS ✨

void ufshcd_rmwl (struct ufs_hba *hba , u32 mask , u32 val , u32 reg );

🎀 ARGUMENTS 🎀

• hba — per adapter instance. It's giving "which controller are we talking about?" energy. 👑
• mask — mask to apply on read value. 🎭
• val — actual value to write. ✍️
• reg — register address. 📍
