Hi Bruce,

When userspace program try to initialize full duplex SPI transaction 
through ioctl system call to SPIDEV driver, SPIDEV driver return 
"invalid argument" to userspace program.

There are 4 patches modify the size of the structure used by SPIDEV 
driver and this revert is fix the issue introduced by 4 of the 
patches. 

950a0f4 spi: modify spidev_test to test modifying FIFO trigger level 
during runtime
db6b515 spi/pxa2xx: Add new ioctl for configuring FIFO trigger level 
in runtime
c455485 spi: modify spidev_test to test automatic PIO/DMA switching 
afe9c4b spi/pxa2xx: auto switch between PIO and DMA with 
configurable threshold size

These patches are targeted for linux-yocto-3.14 kernel 
standard/valleyisland branch.

Kindly review the patches and merge if there is no issue.
Thank you.

Chai, Chong Yi
