linux-next: build failure after merge of the drm-misc tree

[Stephen Rothwell]

Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/tee/tee_shm.c:87:2: error: unknown field 'kmap_atomic' specified in initializer
  .kmap_atomic = tee_shm_op_kmap_atomic,
  ^
drivers/tee/tee_shm.c:87:17: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .kmap_atomic = tee_shm_op_kmap_atomic,
                 ^
drivers/tee/tee_shm.c:87:17: note: (near initialization for 'tee_shm_dma_buf_ops.begin_cpu_access')
drivers/tee/tee_shm.c:88:2: error: unknown field 'kmap' specified in initializer
  .kmap = tee_shm_op_kmap,
  ^
drivers/tee/tee_shm.c:88:10: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]

          ^
drivers/tee/tee_shm.c:88:10: note: (near initialization for 'tee_shm_dma_buf_ops.end_cpu_access')

Caused by commit

  f9b67f0014cb ("dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro")

interacting with commit

  967c9cca2cc5 ("tee: generic TEE subsystem")

from the arm-soc tree.

I applied the following merge fix patch for today:

Thanks Stephen. Looks good to me.

This merge fix is now needed when I merge the drm tree (as Dave merged
the drm-misc tree).

Since this is an all-new driver it might be best to stagger the pull
requests and merge the new tee subsystem (or whatever it is) after drm?

Not sure what to best do here ...

This will merge via Dave, so Dave just needs to let Linus know that a
fix up is needed when this merges with the arm-soc stuff in Linus' tree.

The TEE subsystem is currently on a separate branch by itself in arm-soc,
so we could easily delay that until DRM is in, and point out the resolution
here.

Dave is somewhere without mail, but I chatted with him quickly and he
agrees this seems simplest. drm-next main pull should go out somewhere
tomorrow he said.
