Larry Finger 57f1d4d39e staging: gdm724x: Remove tests of KERNELVERSION
Kernel code need not test for KERNELVERSION. Besides being unnecessary
for an in-kernel driver, these lines will cause a build failure for any
source tree with a stale include/linux/version.h.

This patch is only compile tested.
