`kmod-ipt-coova`: Fails to build with `/src/linux/xt_coova.c:332:11: error: passing argument 4 of 'proc_create_data' from incompatible pointer type [-Werror=incompatible-pointer-types]`.

[dreirund]

Ahoj,

when I try to build kmod-ipt-coova from the HandsomeMod/packages feed, it fails with /src/linux/xt_coova.c:332:11: error: passing argument 4 of 'proc_create_data' from incompatible pointer type [-Werror=incompatible-pointer-types].

After a failing make -j6, here the terminal output of
make -j1 V=sc package/feeds/packages/coova-chilli/compile:
