🌸 spi_nor_init_erase_cmd(9) 🌸

okay bestie, welcome to the Kernel API Manual page for spi_nor_init_erase_cmd(9) — title and manual name are both folded in near the top, cute and accounted for. 💅

---

🎀 NAME 🎀

spi_nor_init_erase_cmd — initialize an erase command. that's the whole assignment, and it ate. ✨

---

✨ SYNOPSIS ✨

struct spi_nor_erase_command * spi_nor_init_erase_cmd (const struct
spi_nor_erase_region *region , const struct spi_nor_erase_type *erase );

---

🫶 ARGUMENTS 🫶

• region — pointer to a structure that describes a SPI NOR erase region. literally handing over the region info. 🗺️
• erase — pointer to a structure that describes a SPI NOR erase type. the erase-type info, slay. 💅

---

💫 RETURN 💫

the pointer to the allocated erase command, ERR_PTR(-errno) otherwise. so you either get the command pointer or the error-pointer situation; no cap. 💀
