Mike Rapoport f64dcac0b1 backlight: tdo24m: ensure chip select changes between transfers 
Some SPI host drivers do not change chip select betwen transfers unless
.cs_chnage field is explicitly set. The LCD spec requires chip select
change between consecuitive transfers, so ensure it at the SPI driver
level.

Anton Vorontsov e0626e3844 spi: prefix modalias with "spi:" 
This makes it consistent with other buses (platform, i2c, vio, ...).  I'm
not sure why we use the prefixes, but there must be a reason.

This was easy enough to do it, and I did it.
