nvmem_cell_...iable_le_u32(9)

💅 NAME 💅

nvmem_cell_read_variable_le_u32 — bestie, this one reads up to 32-bits of data and hands it to you as a little endian number ✨

So real quick before we get into it: this is from the Kernel API Manual (nvmem_cell_...iable_le_u32(9)), and it's lowkey the "idk how many bytes this cell has, just gimme" girlie of the nvmem family. 🎀

✨ SYNOPSIS ✨

int nvmem_cell_read_variable_le_u32(struct device *dev, const char *cell_id, u32 *val);

🫶 ARGUMENTS 🫶

• dev — the device that's requesting the nvmem cell. like, whose cell is it? this one 🫵
• cell_id — the name of the nvmem cell you wanna read. yes it's a string, yes you need to spell it right 💀
• val — pointer to the output value. she's an output param, she gets filled in, don't forget to pass a real pointer ok 😭

🌈 RETURN 🌈

0 on success, or a negative errno. that's it, that's the vibe check — zero means slay, negative means something went sideways 🙈
