[PATCH v2 0/1] spi: spi-fsl-qspi: call spi_unregister_controller

Changes since v1: * use devm_spi_register_controller() instead of calling spi_unregister_controller() in the remove function Thanks Volker Volker Haspel (1): spi: spi-fsl-qspi: use devm_spi_register_controller drivers/spi/spi-fsl-qspi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion

[PATCH v2 1/1] spi: spi-fsl-qspi: use devm_spi_register_controller

The driver does not clearly unregister the spi controller. Therefore calling an unbind and bind again will end up in a Kernel crash. The function devm_spi_register_controller will automatically be unregister the SPI device. Signed-off-by: Volker Haspel Signed-off-by: John Ogness --- drivers

[PATCH] spi: spi-fsl-qspi: call spi_unregister_controller

The driver does not clearly unregister the spi controller. Therefore calling an unbind and bind again will end up in a Kernel crash. Each driver who calls spi_register_controller() in the probe function has to call spi_unregister_controller() too. Signed-off-by: Volker Haspel Signed-off-by: John
