Issue: FP identification is not working immediately after entering wrong password
System prerequisite: FP enrolled on system, Identify works fine.
OS: Verified on: 20.04 PPA release.
• Lock the screen
• Enter wrong regular password and press enter.
• Observe that "please try again" error is shown.
• Now try to login using enrolled FP. Observe that FP gets detected (FW uart log shows that FP is detected) but there will be no change in the login screen.
• Need to enter password to login into user account or Hit enter again, login screen will show the Swipe your finger option and FP identify works.
Attached the fprintd debug log.
Events actions are mentioned with this symbol <==> at attached output.
Post wrong password attempt, FW is immediately ready to capture the finger, but host is saying device is already claimed and acquiring after hitting enter key again.
