-Subject: [PATCH] spi: sync up initial chipselect state
-
-When initially probing the SPI slave device, the call for disabling an
-SPI device without the SPI_CS_HIGH flag is not applied, as the
-condition for checking whether or not the state to be applied equals the
-one currently set evaluates to true.
-
-This however might not necessarily be the case, as the chipselect might
-be active.
-
-Add a force flag to spi_set_cs which allows to override this
-early access condition. Set it to false everywhere except when called
-from spi_setup to sync up the initial CS state.
-
-Fixes commit d40f0b6f2e21 ("spi: Avoid setting the chip select if we don't
-need to")
