I agree that this is a problem, but I think I would prefer if we just made a
stub function for adreno_show instead of doing a inline ifdef, so in
adreno_gpu.c:
#ifdef defined(CONFIG_DEBUG_FS) || defined(CONFIG_DEV_COREDUMP)
...
#else
void adreno_show(struct msm_gpu *gpu, msm_gpu_state *state,
struct drm_printer *p)
{
}
#endif
If you want, I can do a quick patch.
