Hi Grant, After merging the spi tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/mmc/host/mmc_spi.c: In function 'mmc_spi_readbytes': drivers/mmc/host/mmc_spi.c:185: error: implicit declaration of function 'spi_sync_locked' drivers/mmc/host/mmc_spi.c: In function 'mmc_spi_request': drivers/mmc/host/mmc_spi.c:1088: error: implicit declaration of function 'spi_bus_lock' drivers/mmc/host/mmc_spi.c:1101: error: implicit declaration of function 'spi_bus_unlock' Caused by commit f0168ff4069fba07fdd4b05aa19f283171c8d265 ("spi/mmc_spi: mmc_spi adaptations for SPI bus locking API"). Maybe updates to another file were missed? I have used the spi tree from next-20100628 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
