[SCSI] mpt2sas: Null pointer deference possibility in mpt2sas_ctl_event_callback function
Added a check to identify if mpi_reply is NULL in mpt2sas_ctl_event_callback() and return without proceeding if it is the case. Also modified the following functions to return void instead of 0 or 1 as returning those values from events perspective doesn't make sense. * _base_async_event() * mpt2sas_ctl_event_callback() * mpt2sas_scsih_event_callback() Signed-off-by: Sreekanth Reddy <Sreekanth.Reddy@lsi.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
