okay so welcome to the Kernel API Manual, bestie 🫶. This one is v4l2_fh_is_singular_file, and she returns 1 if this filehandle is the only filehandle opened for the associated video_device. no cap, that’s the whole vibe check 💖.

🌸 SYNOPSIS

int v4l2_fh_is_singular_file (struct file *filp );

🎀 ARGUMENTS

• filp — pointer to struct file. that’s it, she’s a pointer, iconic 💅.

✨ DESCRIPTION

This is a helper function variant of v4l2_fh_is_singular that uses struct file as its argument. lowkey a little sister function, but make it file-flavored 🦋.

If filp->private_data is NULL, then it will return 0. so like, null private data? she’s giving zero, literally 💀.
