Hi Mark, After merging the spi tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/spi/spi-fsl-dspi.c: In function 'dspi_setup': drivers/spi/spi-fsl-dspi.c:395:2: error: implicit declaration of function 'ns_delay_scale' [-Werror=implicit-function-declaration] ns_delay_scale(&pcssck, &cssck, cs_sck_delay, clkrate); ^ Caused by commit f9d9c83fcf09 ("Merge branch 'fix/fsl-dspi' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi into spi-fsl-dspi") which removed the function that was added (and referenced) in one of its parents. I have used the spi tree from next-20150402 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
