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]
.kmap = tee_shm_op_kmap,
^
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:
