Hi all,

After merging the kspp tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/md/dm-verity-loadpin.c: In function 'dm_verity_loadpin_is_bdev_trusted':
drivers/md/dm-verity-loadpin.c:61:13: error: implicit declaration of function 'dm_table_get_num_targets'; did you mean 'dm_table_resume_targets'? [-Werror=implicit-function-declaration]
   61 |         if (dm_table_get_num_targets(table) != 1)
      |             ^~~~~~~~~~~~~~~~~~~~~~~~
      |             dm_table_resume_targets
drivers/md/dm-verity-loadpin.c:64:14: error: implicit declaration of function 'dm_table_get_target'; did you mean 'dm_table_add_target'? [-Werror=implicit-function-declaration]
   64 |         ti = dm_table_get_target(table, 0);
      |              ^~~~~~~~~~~~~~~~~~~
      |              dm_table_add_target
drivers/md/dm-verity-loadpin.c:64:12: error: assignment to 'struct dm_target *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
   64 |         ti = dm_table_get_target(table, 0);
      |            ^

Caused by commit

  b6c1c5745ccc ("dm: Add verity helpers for LoadPin")

interacting with commits

  2aec377a2925 ("dm table: remove dm_table_get_num_targets() wrapper")
  564b5c5476cd ("dm table: audit all dm_table_get_target() callers")

from the device-mapper tree.

I have applied the following merge fix patch for today.
