Subject: [PATCH v11 02/14] mtd: spi-nor: core: add spi_nor_controller_ops_erase helper
Date: Thu, 23 Jul 2020 18:41:51 +0530
Message-ID: <20200723131203.40916-3-me@yadavpratyush.com> (raw)
In-Reply-To: <20200723131203.40916-1-me@yadavpratyush.com>

From: Pratyush Yadav <p.yadav@ti.com>

It is a thin wrapper around nor->controller_ops->erase(). In a future
commit DTR support will be added. These ops can not be supported by the
erase() hook and this helper will make it easier to reject those calls.
