           struct device *device;
           struct linedisp *linedisp;
           bool direct;
        };

💖 Members 💖

• list — List entry for the linedisp_attachments list. lowkey just the linked-list hookup that keeps everything connected 💅

• linedisp — Pointer to the linedisp mapped to the device. the actual linedisp bestie in this situationship 🫶
• direct — true for directly attached device using linedisp_attach, false for child registered device using linedisp_register. this is the vibe check: direct attachment vs. child registration, fr fr 🦋
