[PATCH 1/5] scsi: mpt3sas: fix Mpi2SCSITaskManagementRequest_t TaskMID handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The TaskMID field of sturtc Mpi2SCSITaskManagementRequest_t seems to be
a 16-bits little endian value but is not declared as such, causing
sparse to generate warnings. Change this field declaration to __le16 and
fix a test in _ctl_set_task_mid() to avoid sparse warnings.
