Comment 38 for bug 53923

Interesting thing here:
I've compiled above module in the working kernel: 2.6.20-12, and it just compile well.
(tifm module version 0.8)
On kernel 2.6.20-14 that doesn't works:
root@leon:/home/laurent# make clean
rm -rf *.o *.o.d *.ko.d .depend .*.cmd *.ko *.mod.c .tmp_versions
root@leon:/home/laurent# make
echo /home/laurent
/home/laurent
make -C /lib/modules/2.6.20-14-generic/build M=/home/laurent

It seems that kernel-2.6.20-14 is missing linux/mmc/protocol.h ??

Could it be a related to why the module don't works well on -13 and -14??
