devm_mux_chip_alloc(9)

okay so bestie, welcome to devm_mux_chip_alloc(9) from the Kernel API Manual 💖 — it's the resource-managed version of mux_chip_alloc(), and yes it's giving kernel-core main character energy ✨

🎀 NAME 🎀

devm_mux_chip_alloc — resource-managed version of mux_chip_alloc(). that's the whole name, no cap 💅

✨ SYNOPSIS ✨

the signature is right here, bestie — copy it exactly:

       struct mux_chip * devm_mux_chip_alloc (struct device *dev , unsigned int
       controllers , size_t sizeof_priv );

💅 ARGUMENTS 💅

• dev — the parent device implementing the mux interface, aka the main character holding it down.
• controllers — the number of mux controllers to allocate for this chip.
• sizeof_priv — the size of the extra memory area that's for private use by the caller.

🦋 DESCRIPTION 🦋

for the full lore, check mux_chip_alloc — it's got more details, periodt.

🌈 RETURN 🌈

you get a pointer to the new mux-chip, or an ERR_PTR with a negative errno — that's the vibe check result, bestie.
