Subject: [PATCH 03/20] lightnvm: fix capabilities for 2.0 sysfs
Date: Wed, 21 Feb 2018 10:26:41 +0100	[thread overview]
Message-ID: <1519205218-26994-4-git-send-email-javier@cnexlabs.com> (raw)
In-Reply-To: <1519205218-26994-1-git-send-email-javier@cnexlabs.com>

Both 1.2 and 2.0 specs define a field for media and controller
capabilities. Also, 1.2 defines a separate field dedicated to device
capabilities.

In 2.0 sysfs, this values have been mixed. Revert them to the right
value.
