[PATCH 4.9 024/207] spi: spl022: fix Microwire full duplex mode

From: Thomas Perrot <redacted>

[ Upstream commit d81d0e41ed5fe7229a2c9a29d13bad288c7cf2d2 ]

There are missing braces in the function that verify controller parameters,
then an error is always returned when the parameter to select Microwire
frames operation is used on devices allowing it.
