From: Emilio G. Cota <[email protected]> buf_unalloc() frees the memory buffers allocated with vme_alloc_consistent. The associated VME resource is needed in both vme_alloc_consistent and vme_free_consistent; however the slave VME resources are being freed before the calls to vme_free_consistent are made, which means the buffers are never returned.
Fix this by freeing the VME resources only after the consistent buffers have been returned. Signed-off-by: Emilio G.
