Subject: [PATCH v2 04/19] nvmem: Do not use DEVFS_IS_CHARACTER_DEV
Date: Mon, 28 Jan 2019 22:55:34 -0800	[thread overview]
Message-ID: <20190129065549.29161-5-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190129065549.29161-1-andrew.smirnov@gmail.com>

There doesn't appear any good reason to mark NVMEM cdevs as
DEVFS_IS_CHARACTER_DEV, since NVMEM devices should be able to
read/write data at arbitrary offsets and are not different from any
other cdevs representing non-volatile storage.
