spmi_device_alloc(9)

💖 NAME 💖

spmi_device_alloc — Allocate a new SPMI device ✨

okay so this is spmi_device_alloc(9) from the Kernel API Manual, and it's literally the helper that allocates a new SPMI device 💅

✨ SYNOPSIS ✨

struct spmi_device * spmi_device_alloc (struct spmi_controller *ctrl );

🎀 ARGUMENTS 🎀

• ctrl — the associated controller 🎛️

🦋 DESCRIPTION 🦋

so here's the vibe check, bestie: the caller is responsible for either calling spmi_device_add to add the newly allocated controller, or calling spmi_device_put to discard it. that's the whole contract — you get the fresh allocation, then you either add it or put it 💖

no cap: spmi_device_add adds it, spmi_device_put discards it. those are the two paths, and the caller has to pick one ✨
