spi_nor_otp_is_locked_sr2(9)

NAME 🎀

okay bestie, welcome to the Kernel API Manual page for spi_nor_otp_is_locked_sr2(9) — and this function is literally here to get the OTP region lock status. That's the whole assignment, no cap. 💅

---

SYNOPSIS ✨

int spi_nor_otp_is_locked_sr2 (struct spi_nor *nor , unsigned int region
       );

---

ARGUMENTS 🦋

• nor — pointer to struct spi_nor. That's the struct pointer you're handing over, bestie.
• region — the OTP region. Yep, the region we're checking for lock status.

---

DESCRIPTION 🌸

So what this does: it retrieves the OTP region lock bit by reading the status register-2. That's the method, periodt.

This method is used on GigaDevice and Winbond flashes. Iconic behavior, honestly. 🔥

RETURN 🌈

• 0 on success.
• -errno otherwise.

So yeah: zero means slay, and a negative -errno means the error vibe check did not pass. 💀
