Deprecation: #78314 - AbstractFunctionModule->getBackPath

See forge#78314

Description

The protected method AbstractFunctionModule->getBackPath() has been marked as deprecated, as it is not needed anymore.

Impact

Calling the PHP method will trigger a deprecation log entry.

Affected Installations

Any TYPO3 extension with a PHP class extending the AbstractFunctionModule and calling the method above.

Migration

As the method always returns an empty string (since the backPath functionality is not needed anymore) the PHP call can be removed.
