Hi Mark, After merging the spi tree, today's linux-next build (x86_64_allmodconfig) failed like this: drivers/spi/spi-cadence.c: In function 'cdns_spi_write': drivers/spi/spi-cadence.c:135:2: error: implicit declaration of function 'writel_relaxed' [-Werror=implicit-function-declaration] writel_relaxed(val, xspi->regs + offset); ^ Caused by commit c474b3866546 ("spi: Add driver for Cadence SPI controller"). I have used the spi tree from next-20140414 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
