Merge branch 'spi/next' of git://git.secretlab.ca/git/linux-2.6
* 'spi/next' of git://git.secretlab.ca/git/linux-2.6: spi/amba-pl022: work in polling or interrupt mode if pl022_dma_probe fails spi/spi_s3c24xx: Use spi_bitbang_stop instead of spi_unregister_master in s3c24xx_spi_remove spi/spi_nuc900: Use spi_bitbang_stop instead of spi_unregister_master in nuc900_spi_remove spi/spi_tegra: use spi_unregister_master() instead of spi_master_put() spi/spi_sh: use spi_unregister_master instead of spi_master_put in remove path spi: Use void pointers for data in simple SPI I/O operations spi/pl022: use cpu_relax in the busy loop spi/pl022: mark driver non-experimental spi/pl022: timeout on polled transfer v2 spi/dw_spi: improve the interrupt mode with the batch ops spi/dw_spi: change poll mode transfer from byte ops to batch ops spi/dw_spi: remove the un-necessary flush() spi/dw_spi: unify the low level read/write routines
