Subject: [PATCH 4/5] common: globvar: let nvvar_remove() report non-existing variable
Date: Mon, 30 Oct 2017 11:34:20 +0100	[thread overview]
Message-ID: <20171030103421.15353-5-ejo@pengutronix.de> (raw)
In-Reply-To: <20171030103421.15353-1-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.
