spi: quad: fix the name of DT property in patch The previous property name spi-tx-nbits and spi-rx-nbits looks not human-readable. To make it consistent with other devices, using property name spi-tx-bus-width and spi-rx-bus-width instead of the previous one specify the number of data wires that spi controller will work in.

2013-08-31spi: core: Fix spi_register_master error handlingAxel Lin1-1/+1
In the case spi_master_initialize_queue() fails, current code calls device_unregister() before return error from spi_register_master(). However, all the drivers call spi_master_put() in the error path if spi_register_master() fails. Thus we should call device_del() rather than device_unregister() before return error from spi_register_master(). This also makes all the spi_register_master() error handling consistent, because all other error paths of spi_register_master() expect drivers to call spi_master_put() if spi_register_master() fails.

2013-08-31spi: rspi: Add spi_master_get() call to prevent use after freeAxel Lin1-1/+1
In rspi_remove(), current code dereferences rspi after spi_unregister_master(), thus add an extra spi_master_get() call is necessary to prevent use after free. Current code already has an extra spi_master_put() call in rspi_remove(), so this patch just adds a spi_master_get() call rather than a spi_master_get() with spi_master_put() calls.
