Subject[PATCH linux-next] Documentation: mic: mpssd: Disable mpssd builds for kernels < 3.13
Date
mpssd depends on headers available in kernels >= 3.13. Therefore
disable the build for kernels < 3.13. For kernels < 3.13, to avoid the
appearance of a build break simply print an error message and exit.
