Description

in […]/typo3/sysext/backend/Classes/Controller/LoginController.php line 412

(1/1) TypeError
trim() expects parameter 1 to be string, null given

  $logoAlt = trim($extConf['loginLogoAlt']);

The issue is that the loginLogoAlt index is accessed without checking availability.
Threfore a null coalescing operator should be added.
