  "message": "Blackfin SPI Driver: fix bug - correct usage of struct spi_transfer.cs_change\n\nAccording to comments in linux/spi/spi.h:\n\n * All SPI transfers start with the relevant chipselect active.  Normally\n * it stays selected until after the last transfer in a message. Drivers\n * can affect the chipselect signal using cs_change.\n *\n * (i) If the transfer isn\u0027t the last one in the message, this flag is\n * used to make the chipselect briefly go inactive in the middle of the\n * message.  Toggling chipselect in this way may be needed to terminate\n * a chip command, letting a single spi_message perform all of group of\n * chip transactions together.\n *\n * (ii) When the transfer is the last one in the message, the chip may\n * stay selected until the next transfer.  On multi-device SPI busses\n * with nothing blocking messages going to other devices, this is just\n * a performance hint; starting a message to another device deselects\n * this one.  But in other cases, this can be used to ensure correctness.\n * Some devices need protocol transactions to be built from a series of\n * spi_message submissions, where the content of one message is determined\n * by the results of previous messages and where the whole transaction\n * ends when the chipselect goes intactive.\n\nSigned-off-by: Yi Li \u003cyi.li@analog.com\u003e\nSigned-off-by: Bryan Wu \u003ccooloney@kernel.org\u003e\nAcked-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
