[PATCH] spi: spi-mem: Constify spi_mem->name

[Boris Brezillon <boris.brezillon@xxxxxxxxxxx>]

There is no reason to make spi_mem->name modifiable. Moreover,
spi_mem_ops->get_name() returns a const char *, which generates a gcc
warning when assigning the value returned by spi_mem_ops->get_name()
to spi_mem->name.

Fixes: 5d27a9c8ea9e ("spi: spi-mem: Extend the SPI mem interface to set a custom memory name")
