Subject: mtd: m25p80: Call spi_mem_get_name() to let controller set a custom
name
Git-commit: b02b17f55b2e789b9747cf4dd2eaaa110439a4cc
Patch-mainline: v4.19-rc1
References: fate#326572
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
