PATCH v2: Arla CVS Current on Linux 2.6.34 to 3.18
Hello,
I have corrected two things in the existing patch:
Before I forgot two include files that is stored higher up in the
direvtory hierarchy.
And I have changed the syntax of the preprocessor statements to what was
used in the rest of the driver.
I have tested that this patch compiles clean on ALL kernels from 2.6.34 to
3.18.
