i2c_mark_adapter_resumed(9)

✨ i2c_mark_adapter_resumed ✨

okay bestie, so this one is a kernel API manual page, and honestly? it's giving tiny-but-mighty. it's literally one function and it fixes a whole vibe 💅

---

🌸 NAME 🌸

i2c_mark_adapter_resumed — the helper that tells the core "we're so back", aka it reports the resumed state of the adapter to the core 🦋

---

🎀 SYNOPSIS 🎀

void i2c_mark_adapter_resumed (struct i2c_adapter *adap );

---

💖 ARGUMENTS 💖

• adap — the adapter you're marking as resumed. that's it, that's the whole argument. she's lowkey a one-job icon 👑

---

✨ DESCRIPTION ✨

so when you use this helper to mark an adapter as resumed, the core will allow further transfers to this adapter. yes, that's the whole plot. she said "transfers? unlocked." 🔥

also, bestie, there's a pointer: see also the further notes over at i2c_mark_adapter_suspended. go read that one too, iykyk 🙈
