This is simply a diff against to the corresponding file in alsa-kernel
tree. If older kernels require some changes (e.g. ifdef's), we patch
it locally in alsa-driver tree at building.
In the case of asihpi, it's generated like:
% cd alsa-driver/pci/asihpi
% diff -u ../../alsa-kernel/pci/asihpi/hpios.c hpios.c > hpios.patch

If your change in the kernel conflicts with the existing patch, yes,
it'd be appreciated if you give the patch, too. Usually I make a
patch by myself.
