compat: allow compililation with kernels with updated sound drivers
From: Mauro Carvalho Chehab <mchehab@infradead.org>
A few distro kernels, like Mandriva 2.6.22.9-desktop-1mdv are starting to be
shipped with the newer alsa drivers. This patch changes the compat code for
older kernels in a way that it will be compatible also with those distro
kernels.
