[PATCH] spi: Kill superfluous cast in spi_w8r16()

[PATCH] spi: Kill superfluous cast in spi_w8r16()

[Geert Uytterhoeven]

From: Geert Uytterhoeven <geert+renesas-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>

spi_write_then_read() takes a "void *" for rxbuf, so there's no need to
cast the buffer pointer to "u8 *".
