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.

Obviously the of_device_id table name is wrong. Fix below build error: CC [M] drivers/spi/spi-efm32.o drivers/spi/spi-efm32.c:499:1: error: '__mod_of_device_table' aliased to undefined symbol 'efm32_uart_dt_ids' make[2]: *** [drivers/spi/spi-efm32.o] Error 1 make[1]: *** [drivers/spi] Error 2 make: *** [drivers] Error 2 Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>

The Altera SPI hardware can be configured to support data width from 1 to 32 since Quartus II 8.1. To avoid truncation by integer division, use DIV_ROUND_UP to calculate hw->bytes_per_word.

The code in nuc900_slave_select() supports handling SPI_CS_HIGH. Thus set SPI_CS_HIGH bit in master->mode_bits to make it work. Otherwise, spi_setup() will return unsupported mode bits error message if SPI_CS_HIGH is set in the mode field of struct spi_device.

Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. This patch also removes the label exit_busy, to use the error code returned by the failing operation, rather than always -EBUSY.

This patch simplifies the code and makes it better in readability. Now the logic in the while loop is simply "write to ALTERA_SPI_TXDATA then read from ALTERA_SPI_TXDATA". There is a slightly logic change because now we avoid a read-write cycle when hw->len is 0. Since the code in bitbang library will call bitbang->txrx_bufs() only when t->len is not 0, this is not a problem.
