commit: a9c4ae108610716140bdec56ae0bebbe1c5cbe49 [58/85] scsi: qla2xxx: Use get_unaligned_*() instead of open-coding these functions
reproduce:
         # apt-get install sparse
         # sparse version: v0.6.1-129-g341daf20-dirty
         git checkout a9c4ae108610716140bdec56ae0bebbe1c5cbe49
         make ARCH=x86_64 allmodconfig
         make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag

Because I think that I don't have introduced any new endianness issues 
with the mentioned patch, please ignore this kernel test robot report. 
I'm working on patches that make the qla2xxx driver endianness clean.
