Subject: [PATCH 5/5] common: globvar: let nvvar_remove() report non-existing variable
Date: Wed, 13 Sep 2017 14:23:32 +0200 [thread overview]
Message-ID: <20170913122332.17585-6-ejo@pengutronix.de> (raw)
In-Reply-To: <20170913122332.17585-1-ejo@pengutronix.de>
The former implementation did not allow to detect whether the call to
nvvar_remove() succeeded or failed and always returned 0.
This changes the implementation to return 0 only if a variable with the
given name was found and return ENOENT otherwise.
