-Subject: [PATCH] spi: Make GPIO CSs honour the SPI_NO_CS flag
-
-The SPI configuration state includes an SPI_NO_CS flag that disables
-all CS line manipulation, for applications that want to manage their
-own chip selects. However, this flag is ignored by the GPIO CS code
-in the SPI framework.
-
-Correct this omission with a trivial patch.
