Subject: [PATCH v3 3/3] mtd: m25p80: Call spi_mem_get_name() to let controller set a custom name
Date: Thu, 2 Aug 2018 14:53:54 +0200 [thread overview]
Message-ID: <1533214434-28761-4-git-send-email-frieder.schrempf@exceet.de> (raw)
In-Reply-To: <1533214434-28761-1-git-send-email-frieder.schrempf@exceet.de>
By calling spi_mem_get_name(), the driver of the (Q)SPI controller can
set a custom name for the memory device if necessary.
This is useful to keep mtdparts compatible when controller drivers are
ported from the MTD to the SPI layer.
