#ifdef HIDAPI_ALLOW_BUILD_WORKAROUND_KERNEL_2_6_39
/* This definitions first appeared in Linux Kernel 2.6.39 in linux/hidraw.h.
hidapi doesn't support kernels older than that,
so we don't define macros below explicitly, to fail builds on old kernels.
For those who really need this as a workaround (e.g. to be able to build on old build machines),
can workaround by defining the macro above.
