If anyone has any objections, please let me know. ------------------ From: Chintan Patel [ Upstream commit c2925992232fdc4e90f030b77e7867921db071b5 ] The sh_mobile_lcdc driver exposes overlay configuration via sysfs, but the core driver does not require CONFIG_FB_DEVICE. Make overlay sysfs optional so that the driver can build and operate even when FB_DEVICE is disabled. The kernel naturally ignores the missing attribute group, preserving buildability and type safety.
