Subject: [PATCH] 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.
