 hardware: does the patch below against current kernel make a difference?

The 3.13 source was installed using "apt-get source linux-source-3.13.0"

The patch hunk#2 failing issue is something in the "heredoc" notation 
(me trying to apply the patch without storing the patch lines as 
temporary input file). I am now using the temp file without any issue.

The next newly blocking issue is this:

# make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
make: Entering directory `/usr/src/linux-headers-3.17.0-031700rc7-generic'

Any new suggestion how to honour your patch/test request?
