adis_write_reg(9)

✨ adis_write_reg(9) ✨

okay so real talk, this one lives in the Kernel API Manual and it's genuinely one of the cutest little helpers in the IIO/IMU corner of the kernel — it's the function that yeets N bytes into a register on an adis device. let's get into it bestie 🎀

🌸 NAME 🌸

adis_write_reg — write N bytes to register 💅

🦋 SYNOPSIS 🦋

int adis_write_reg (struct adis *adis , unsigned int reg , unsigned int
     val , unsigned int size );

🌈 ARGUMENTS 🌈

• adis — the adis device 🫶 like, the actual device struct you're poking at.
• reg — the address of the lower of the two registers. yep, lower — that detail matters, don't come for me.
• val — the value you're writing to the device. it can be up to 4 bytes, so keep it in range bestie 🙈
• size — the size of that value, and it's measured in bytes.

👑 RETURN 👑

0 on success, and a negative error code otherwise. so like, zero = slay, negative = something went sideways 😭
