This series mainly fixes racing problems btw err_handler and paths like
system PM ops, async scan and task abort callback. 

This series has been tested with error/fault injections to system PM
operations, async scan and task abort to the UFS device W-LU.

Can Guo (2):
  scsi: ufs: Serialize eh_work with system PM events and async scan
  scsi: ufs: Fix a racing problem between ufshcd_abort and eh_work
