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); ^
