Subject: spi: sifive: Tidy up dm_spi_slave_platdata variable
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e67cd814ee2d00e1b8651bc1cd889ac6f45ed26b;p=u-boot.git

spi: sifive: Tidy up dm_spi_slave_platdata variable

Usually variable name slave is used for spi_slave structure
and slave_plat for the dm_spi_slave_platdata.

Let's follow this meaningful notation by replacing slave
with slave_plat for dm_spi_slave_platdata structure.
