spi: Remove extra/duplicate constant from expression

[PATCH] spi: Remove extra/duplicate constant from expression

Posted by Deepak R Varma 2 years, 7 months ago

Constant SPI_TX_OCTAL is included twice while building the controller
mode bits. Remove the extra constant.
Issue identified using doublebitand.cocci Coccinelle semantic patch.
