of_changese...op_u32_array(9)

okay bestie, welcome to the of_changese...op_u32_array(9) page from the Kernel API Manual ✨ This one is all about adding a 32 bit integer property array to a changeset, and yeah, it's kinda iconic 💅

💖 NAME 💖

of_changeset_add_prop_u32_array — Add a property of 32 bit integers property to a changeset. Yes, the description really says “property” twice, and we're keeping it, periodt 🎀

✨ SYNOPSIS ✨

Here's the exact signature, no cap:

int of_changeset_add_prop_u32_array (struct of_changeset *ocs , struct
device_node *np , const char *prop_name , const u32 *array , size_t sz
);

🎀 ARGUMENTS 🎀

• ocs — changeset pointer. This is the changeset bestie you're working with 🫶
• np — device node pointer. The node in question, slay.
• prop_name — name of the property to be added. Pick your fave name, iykyk.
• array — pointer to an array of 32 bit integers. That's the data vibes.
• sz — number of array elements. Count 'em.

🌸 DESCRIPTION 🌸

Create a property of 32 bit integers and add it to a changeset. That's the whole plot, bestie — short and sweet 😭💖

⭐ RETURN ⭐

0 on success, a negative error value in case of an error. So if you see a negative number, something did not slay 💀
