Subject: [PATCH] Fingerprint data is now stored in one of two ways depending
on the
shipping API version:
For devices shipped before Android P nothing changes, data is stored
under /data/system/users/<user-id>/fpdata/...
Devices shipped from now on will instead store fingerprint data under
/data/vendor_de/<user-id>/fpdata.
Support for /data/vendor_de and /data/vendor_ce has been added to vold.
Bug: 36997597
Change-Id: Ibc7cc33b756f64abe68a749c0ada0ca4f6d92514
Test: manually
