ELAN ARM-M4 (0c9c)

Status: Merged upstream (libfprint MR !568, merged 2026-06-18)

Device ID(s): 04f3:0c9c

This driver is now merged into upstream libfprint (git master). It is not in older released libfprint, so build from libfprint git (or wait for the first release/distro package that includes it) to get it. Entry kept for people still on an older libfprint.
