Subject: [PATCH] [EFL] Use eina_file_ls() in EFL implementation of FileSystem
 listDirectory() https://bugs.webkit.org/show_bug.cgi?id=89976

Patch by Christophe Dumez <christophe.dumez@intel.com> on 2012-06-26
Reviewed by Antonio Gomes.

Rewrite EFL implementation of Filesystem listDirectory() in order to
use eina_file_ls() instead of POSIX C functions. This results in
shorter code.

No new tests, behavior has not changed.

* platform/efl/FileSystemEfl.cpp:
(WebCore::listDirectory):
