commit 8736f8022e532a3c1d8873aac78e1113c6ffc3b9 upstream.
spidev.h uses _IOC_SIZEBITS directly. musl libc does not provide this macro
unless linux/ioctl.h is included explicitly. Fixes build failures like:
In file included from .../host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/sys/ioctl.h:7:0,
from .../build/spidev_test-v3.15/spidev_test.c:20:
.../build/spidev_test-v3.15/spidev_test.c: In function ‘transfer’:
.../build/spidev_test-v3.15/spidev_test.c:75:18: error: ‘_IOC_SIZEBITS’ undeclared (first use in this function)
ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr);
