The kernel source code is incomplete. If you have a Makefile in
ls /lib/modules/`uname -r`/build
you can follow these steps (*):
1) download the full source of your kernel
2) cd linux-...
patch -p1 < ice1712_shortname.patch
3) cd sound/pci/ice1712/
4) replace the content of the Makefile (after copy-and-paste, remember
one tab char and not spaces before "make -C") with
snd-ice1712-objs := ice1712.o delta.o hoontech.o ews.o
obj-m += snd-ice1712.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
5) compile the module
make
ls snd-ice1712.ko
(*) More info in linux/Documentation/kbuild/modules.txt, in particular:
NOTE: "modules_prepare" will not build Module.symvers even if
CONFIG_MODVERSIONS is set; therefore, a full kernel build needs to be
executed to make module versioning work.
