While I downloaded new firmware to eHBA-9600 on KASAN enabled kernel,
I observed three BUGs. This series addresses them.

Changes from v1:
* 2nd patch: Modified to use bitmap helper functions and number of bits
* 1st/3rd patches: Reflected a comment on the list and added Reviewed-by tags

Shin'ichiro Kawasaki (3):
  scsi: mpi3mr: fix alltgt_info copy size in mpi3mr_get_all_tgt_info
  scsi: mpi3mr: use number of bits to manage bitmap sizes
  scsi: mpi3mr: fix missing mrioc->evtack_cmds initialization
