Kees Cook 1ce871de4f scsi: esas2r: Use flex array destination for memcpy() 
In preparation for FORTIFY_SOURCE performing run-time destination buffer
bounds checking for memcpy(), specify the destination output buffer
explicitly, instead of asking memcpy() to write past the end of what looked
like a fixed-size object. Silences future run-time warning:

  memcpy: detected field-spanning write (size 80) of single field "trc + 1" (size 64)

There is no binary code output differences from this change.
