Subject: [PATCH] RESTRICT AUTOMERGE Revoke dev perm if app is upgrading to
|
|
post 23 and perm has pre23 flag
|
|
|
|
If a permission has the "pre23" flag, and an app is upgrading past api
|
|
23, then we should not assume that a "development" permission remains
|
|
granted
|
|
|
|
Fixes: 259458532
|
|
Test: atest RevokeSawPermissionTest
