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.

Hm, not sure you can do that without breaking setup that pass a
flash_platform_data object with a name.
Also, you should keep the name extracted from the label property if any
(this is done earlier, when spi_nor_set_flash_node() is called).
if (data && data->name)
nor->mtd.name = data->name;
if (!nor->mtd.name)
nor->mtd.name = spi_mem_get_name(spimem);
I missed both facts, that data could be passed with a name assigned
already and that spi_nor_set_flash_node() might assign a name from dt.
I should have looked at the code more closely.
Thanks for pointing that out. I'll fix it.
