Fix build breakage with kernels lower than 2.6.28
From: Mauro Carvalho Chehab <mchehab@redhat.com>
This patch fixes compilation for older kernels. However, due to -alsa
changes on saa7134-alsa and snd-bt878, I'm not sure if this is enough
for it to really work.
I suspect that something else may be needed for they to work with
earlier versions.
Priority: normal
