Subject: [PATCH 3/4] nvmem: make nvmem_device_write/read public
Date: Mon, 18 Jan 2021 21:55:27 +0100	[thread overview]
Message-ID: <20210118205528.9797-3-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20210118205528.9797-1-m.felsch@pengutronix.de>

Those functions already export their symbols so make it public
available. Compared to the nvmem_device_cell_read/write() APIs these
functions are a bit easier to use.
