+Subject: [PATCH] brcmfmac: add stub version of brcmf_debugfs_get_devdir()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In case of compiling driver without DEBUG expose a stub function to make
+writing debug code much simpler (no extra conditions). This will allow
+e.g. using debugfs_create_file() without any magic if or #ifdef.
