bcom_ata_init() declared and assigned a struct bcom_ata_inc *inc that
was never read, tripping clang -Wunused-but-set-variable:

  drivers/dma/bestcomm/ata.c:58:23: error: variable 'inc' set but not
  used [-Werror,-Wunused-but-set-variable]
     58 |         struct bcom_ata_inc *inc;
        |                              ^

Drop the declaration and the bcom_task_inc() call that fed it.
