Erm... this code is defined _only_ for very old kernels just for compatible wrapper, so following the rule for new kernels doesn't make sense.
Then something else is wrong, since this code caused the compilation error(attached below) when I was doing the cross-compilation for the system without PCI for the 2.6.35 kernel (the kernel version was correctly recognized during ./configure):
/root/alsa-driver-1.0.24/acore/wrappers.c: In function 'snd_pci_dev_present': /root/alsa-driver-1.0.24/acore/wrappers.c:200: error: implicit declaration of function 'pci_find_device' make[3]: *** [/root/alsa-driver-1.0.24/acore/wrappers.o] Error 1
Then configure script didn't detect the condition properly. Check CONFIG_HAVE_PCI_DEV_PRESENT in you config.log. Most likely a wrong gcc option or path is given, and the check is screwed up.
