💖 REG_FIELD_PREP16(9) 💖

Okay bestie, welcome to the REG_FIELD_PREP16(9) page from the Kernel API Manual — we're doing u16 bitfield prep today and it's gonna be cute and correct. ✨

🌸 NAME 🌸

REG_FIELD_PREP16 — prepare a u16 bitfield value 🎀

---

🛠️ SYNOPSIS 🛠️

REG_FIELD_PREP16 (__mask , __val );

---

🎀 ARGUMENTS 🎀

• __mask — the shifted mask that defines the field's length and position, iykyk 💅
• __val — the value you're putting in the field 🫶

---

💅 DESCRIPTION 💅

This is the local copy of FIELD_PREP16, bestie. Its whole vibe is:

• generate an integer constant expression ✨
• force u8 😌
• stay consistent with REG_FIELD_GET16, REG_BIT16 and REG_GENMASK16 👑

No cap, that's literally the description. 🦋

---

🔁 RETURN 🔁

__val gets masked and shifted into the field defined by __mask. Slay. 💖
