From 406a6ff5e69fc037506d4f4a90a4f2d27b94acce Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Mon, 30 Apr 2018 10:05:57 -0700 Subject: recovery: Fix the return value when failing to convert to FBE. Test: Build and flash aosp_angler-userdebug. Choose 'Convert to file encryption' from Developer Options. Converting to FBE still works.
