295. Patching kernel 3.7.1 to fix the azx_runtime_suspend bug

(For a general approach to compiling kernel 3.7,see http://verahill.blogspot.com.au/2012/12/compiling-kernel-37-on-debian.html )

Note that it is NOT necessary to patch version 3.7.2

If you're seeing the following error messages during boot of kernel 3.7.0:
snd_hda_intel returns -11
you will want to patch your kernel. Technically I should be patching 3.7, but we might as well go straight for kernel 3.7.1.

So, here's how to patch it:
wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.7.1.tar.bz2
tar xvf linux-3.7.1.tar.bz2
cd linux-3.7.1/
cat /boot/config-`uname -r`>.config
make oldconfig
wget https://patchwork.kernel.org/patch/1865521/raw/
mv index.html hda_intel.patch
patch -i hda_intel.patch -p 1
patching file sound/pci/hda/hda_intel.c Hunk #1 succeeded at 2557 (offset -134 lines). Hunk #2 succeeded at 2571 (offset -134 lines).
make-kpkg clean time fakeroot make-kpkg -j3 --initrd --revision=3.7.1 --append-to-version=-amd64 kernel_image kernel_headers

Once building is complete
mv ../*3.7.1*.deb .
sudo dpkg -i *.deb
and reboot.

Tried it and it works.
