Bug description:
[Impact]
On Ubuntu 20.04, with Synaptics fingerprint reader, users can use one
fingerprint to login system, but if users add more fingerprints, they
still can only one of those to login, other fingerprints do not work.
To fix this issue, we need support fingerprint identification in the driver
of Synaptics fingerprint reader, by backport this libfprint commit to Focal:
https://gitlab.freedesktop.org/libfprint/libfprint/commit/e27b65c9
[Test Case]
I tried backport the commit above to libfprint
(1:1.90.2+tod1-0ubuntu1~20.04.2) in Focal and tested on 3
ThinkPads(both use the 06cb:00bd Synaptics fingerprint reader), the
multiple fingerprints works well.
We have other OEM platforms with Synaptics fingerprint reader, we can
use it to validate the changes if needed.
[Regression Potential]
the commit comes from Synaptics' engineer, just affects one file:
libfprint/drivers/synaptics/synaptics.c, and only add identification
support in that file, so the regression potential should be low.
