# Maintainer: Mikko Nyman <mikko@nyman.xyz>
# Based on the Arch libfprint package by Jan Alexander Steffens (heftig).
#
# Omarchy's fingerprint setup installs this in place of stock libfprint, so
# readers upstream supports ahead of an Arch release reach users by bumping
# the pin here. Pinned to the commit adding the Synaptics reader USB
# 06cb:010b, missing from stock libfprint 1.94.100; the FocalTech MOC support
# carried by the previous pin is retained.
#
# On aarch64 it also carries the aurora driver for Apple Touch ID, which the
# aurora kernel's Secure Enclave driver exposes as /dev/sep-bio
# (aurora-apple-sep.patch, by Chris Kearney). The x86_64 build is unchanged.
# The driver accepts only /dev/sep-bio interface version 4
# (AURORA_BIO_IFACE_VERSION): a kernel that bumps it turns Touch ID off until
# this patch follows, so move the two together.
