If anyone has any objections, please let me know. ------------------ From: Baruch Siach commit a2b4a79b88b24c49d98d45a06a014ffd22ada1a4 upstream. The SPI_IOC_MESSAGE() macro references _IOC_SIZEBITS. Add linux/ioctl.h to make sure this macro is defined. This fixes the following build failure of lcdproc with the musl libc: In file included from .../sysroot/usr/include/sys/ioctl.h:7:0, from hd44780-spi.c:31: hd44780-spi.c: In function 'spi_transfer': hd44780-spi.c:89:24: error: '_IOC_SIZEBITS' undeclared (first use in this function) status = ioctl(p->fd, SPI_IOC_MESSAGE(1), &xfer); ^ Signed-off-by: Baruch Siach Signed-off-by: Mark Brown Signed-off-by: Greg Kroah-Hartman --- include/uapi/linux/spi/spidev.h | 1 + 1 file changed, 1 insertion(+) --- a/include/uapi/linux/spi/spidev.h +++ b/include/uapi/linux/spi/spidev.h @@ -23,6 +23,7 @@ #define SPIDEV_H #include +#include /* User space versions of kernel symbols for SPI clocking modes, * matching
