Hi Mark, Daniel, After merging the spi-mb tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/spi/spi-gpio.c: In function 'spi_gpio_setup': drivers/spi/spi-gpio.c:255:8: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] drivers/spi/spi-gpio.c: In function 'spi_probe_dt': drivers/spi/spi-gpio.c:389:39: error: parameter name omitted drivers/spi/spi-gpio.c: In function 'spi_gpio_probe': drivers/spi/spi-gpio.c:404:2: error: implicit declaration of function 'spi_gpio_probe_dt' [-Werror=implicit-function-declaration] Caused by commit 38ab18caa0ad ("spi: spi-gpio: Add DT bindings"). Please build test these sort of patches with and without CONFIG_OF. I have used the spi-mb tree from next-20120905 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
