Subject: [PATCH V2 1/2] brcmfmac: add stub version of brcmf_debugfs_get_devdir()
Date: Sun,  1 Sep 2019 13:34:35 +0200
Message-ID: <20190901113436.23665-1-zajec5@gmail.com> (raw)

From: Rafał Miłecki <rafal@milecki.pl>

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.
