Subject: [PATCH 1/8] nvmem: core: Set the provider read-only when no write callback is given
Date: Sun, 6 Jan 2019 20:28:13 +0100 [thread overview]
Message-ID: <20190106192820.12558-2-albeu@free.fr> (raw)
In-Reply-To: <20190106192820.12558-1-albeu@free.fr>
If no write callback is given the device should be marked as read-only.
While at it also move from a bit or to a logical or as that is a logical
expression.
