Deprecation: #82702 - Second argument of GeneralUtility::mkdir_deep()

See Issue #82702

Description

The second option of TYPO3\CMS\Core\Utility\GeneralUtility::mkdir_deep() has been marked as deprecated.

Impact

Calling this method with a second argument which is not empty, will trigger a deprecation entry.

Affected Installations

Any installation with a third-party extension calling this method with two arguments.

Migration

Instead of calling GeneralUtility::mkdir_deep(PATH_site . 'typo3temp/', 'myfolder'); the simple syntax GeneralUtility::mkdir_deep(PATH_site . ‘typo3temp/myfolder’); can be used directly, also in TYPO3 v8 and before already.
