Hi all, After merging the spi tree, today's linux-next build (arm multi_v7_defconfig) produced this warning: In file included from include/linux/device.h:15, from include/linux/dmaengine.h:8, from drivers/spi/spi-stm32.c:11: drivers/spi/spi-stm32.c: In function 'stm32_spi_prepare_msg': drivers/spi/spi-stm32.c:1030:20: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=] 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/dev_printk.h:19:22: note: in definition of macro 'dev_fmt' 19 | #define dev_fmt(fmt) fmt | ^~~ drivers/spi/spi-stm32.c:1030:2: note: in expansion of macro 'dev_dbg' 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~ drivers/spi/spi-stm32.c:1030:27: note: format string is defined here 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ~^ | | | int | %ld In file included from include/linux/device.h:15, from include/linux/dmaengine.h:8, from drivers/spi/spi-stm32.c:11: drivers/spi/spi-stm32.c:1030:20: warning: format '%d' expects argument of type 'int', but argument 5 has type 'long unsigned int' [-Wformat=] 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/dev_printk.h:19:22: note: in definition of macro 'dev_fmt' 19 | #define dev_fmt(fmt) fmt | ^~~ drivers/spi/spi-stm32.c:1030:2: note: in expansion of macro 'dev_dbg' 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~ drivers/spi/spi-stm32.c:1030:35: note: format string is defined here 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ~^ | | | int | %ld In file included from include/linux/device.h:15, from include/linux/dmaengine.h:8, from drivers/spi/spi-stm32.c:11: drivers/spi/spi-stm32.c:1030:20: warning: format '%d' expects argument of type 'int', but argument 6 has type 'long unsigned int' [-Wformat=] 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/dev_printk.h:19:22: note: in definition of macro 'dev_fmt' 19 | #define dev_fmt(fmt) fmt | ^~~ drivers/spi/spi-stm32.c:1030:2: note: in expansion of macro 'dev_dbg' 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~ drivers/spi/spi-stm32.c:1030:48: note: format string is defined here 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ~^ | | | int | %ld In file included from include/linux/device.h:15, from include/linux/dmaengine.h:8, from drivers/spi/spi-stm32.c:11: drivers/spi/spi-stm32.c:1030:20: warning: format '%d' expects argument of type 'int', but argument 7 has type 'long unsigned int' [-Wformat=] 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/dev_printk.h:19:22: note: in definition of macro 'dev_fmt' 19 | #define dev_fmt(fmt) fmt | ^~~ drivers/spi/spi-stm32.c:1030:2: note: in expansion of macro 'dev_dbg' 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ^~~~~~~ drivers/spi/spi-stm32.c:1030:59: note: format string is defined here 1030 | dev_dbg(spi->dev, "cpol=%d cpha=%d lsb_first=%d cs_high=%d\n", | ~^ | | | int | %ld Introduced by commit f7005142dace ("spi: uapi: unify SPI modes into a single spi.h header") -- Cheers, Stephen Rothwell
