dpm_resume_start — literally just: Execute "noirq" and "early" device callbacks. that's the whole vibe. 💫

like… the way she references forty other pages and still keeps it cute 😭 that's range, that's growth, that's the whole drivers/base/power directory showing up to support her. 🌈

no technical tea was spilled here that wasn't already in the original, bestie — if you need the real deep lore, go read ./drivers/base/power/main.c 💀
