Subject: [PATCH] spi: spi-amd: remove unused variable

This variable was defined in the original version of this file but
never used, so remove it to avoid the warning:

drivers/spi/spi-amd.c: In function 'amd_spi_fifo_xfer':
drivers/spi/spi-amd.c:171:17: error: unused variable 'opcode' [-Werror=unused-variable]
  171 |  u8 cmd_opcode, opcode = 0;

Fixes: bbb336f39efc ("spi: spi-amd: Add AMD SPI controller driver support")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
