🌸 SYNOPSIS 🌸

void drm_fb_helper_set_suspend (struct drm_fb_helper *fb_helper , bool suspend );

---

🦋 ARGUMENTS 🦋

• fb_helper — the driver-allocated fbdev helper 💅 and yes, it can be NULL, we love a flexible icon.
• suspend — whether to suspend or resume. that's it. that's the bool. 🔥

👑 DESCRIPTION 👑

So basically this is a wrapper around fb_set_suspend, which is implemented by fbdev core — that's the whole vibe. 🌈

But listen: if you don't need to take the lock yourself, use drm_fb_helper_set_suspend_unlocked instead. iykyk 😌

fr fr, pick the right one — the unlocked version exists for a reason, bestie 💖
