From: Pranjal Ramajor Asha Kanojiya <[email protected]>smatch warning: drivers/accel/qaic/qaic_data.c:620 qaic_free_object() error: dereferencing freed memory 'obj->import_attach' obj->import_attach is detached and freed using dma_buf_detach(). But used after free to decrease the dmabuf ref count using dma_buf_put(). drm_prime_gem_destroy() handles this issue and performs the proper clean up instead of open coding it in the driver.
