[PATCH] mtd: m25p80: Call spi_mem_get_name() to let controller set a custom name

From: Frieder Schrempf
Date: Thu Aug 02 2018 - 08:53:54 EST


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.

/* For some (historical?) reason many platforms provide two different
