Date: Wed, 27 Oct 2021 23:25:05 +0200 [thread overview]
Message-ID: <20211027212506.3418521-1-marcel@ziswiler.com> (raw)
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
Today's -next fails building arm64 defconfig as follows:
ERROR: modpost: module drm_cma_helper uses symbol dma_buf_vunmap from
namespace DMA_BUF, but does not import it.
ERROR: modpost: module drm_cma_helper uses symbol dma_buf_vmap from
namespace DMA_BUF, but does not import it.
Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>
Fixes: commit 4b2b5e142ff4 ("drm: Move GEM memory managers into modules")

Changes in v2:
- After consulting the documentation move it to the bottom of the file
where the other MODULE statements are as suggested by Thomas.
- Also move it down there for the drm_gem_shmem_helper.c file.
