✨ spi_nor_post_sfdp_fixups — Kernel API Manual ✨

okay bestie, so this is spi_nor_post_sfdp_fixups(9) from the Kernel API Manual, and honestly? she's a lil cleanup queen 💅

---

🌸 NAME 🌸

spi_nor_post_sfdp_fixups — updates the flash's parameters and settings after SFDP has been parsed. and like, she's only called for flashes that define JESD216 SFDP tables, so if your flash doesn't have those, she simply does not know you 💀

---

🦋 SYNOPSIS 🦋

int spi_nor_post_sfdp_fixups (struct spi_nor *nor );

---

🎀 ARGUMENTS 🎀

• nor — pointer to a struct spi_nor. that's it, that's the whole vibe check for args 🫶

---

💖 DESCRIPTION 💖

so what she actually does? she's used to tweak various flash parameters when the info the SFDP tables handed over is, um, wrong 🙈 not "wrong" like messy-wrong, wrong-wrong. the SFDP tables said something and it's just not it, so this function comes in and fixes the settings. lowkey iconic that someone has to double-check the tables' homework, but here we are ✨
