Subject: [PATCH] nv: add device parameter overwrites to completion list
Date: Thu, 23 Nov 2017 12:02:04 +0100	[thread overview]
Message-ID: <20171123110204.25455-1-s.hauer@pengutronix.de> (raw)

nv variables in the form dev.<devname>.* can be used to make device
parameters persistent. Add these to the completion list to make setting
these variables more convenient.
