| |
Add the compat_ioctl for operations on /dev/spi* so that 32 bit userspace applications can access SPI. As far as I can see all data structure are already prepared for that, so no additional conversion has to be done.
My use case is MIPS with N32 userspace ABI and toolchain, and that was also the platform where I tested it successfully (Cavium Octeon).
