okay bestie, welcome to the Kernel API Manual page for file_to_v4l2_fh(9). it's short, it's sweet, and it's literally about grabbing the right v4l2_fh without being messy. let's get into it 💅

💖 DESCRIPTION 💖

okay so this is the function drivers should use when they need to retrieve the struct v4l2_fh instance pointer that's stored in the file private_data. like, the whole point is that drivers use this function instead of accessing the private_data field directly. that's it. that's the vibe. periodt ✨
