is_dmabuf() has conflicting types between dmabuf.h and dmabuf.c
I was trying to build master of waypipe (to solve another issue) and I wasn't able to build it because in
dmabuf.h the function signature of
int but in
dmabuf.c it is
bool. This is probably some minor issue due to oversight, simply changing the signature in
dmabuf.h solves the issue.
This could be avoided by adding CI checks, but probably isn't nescessary
