git: 78564b68723f - stable/13 - Fix "set but not used" in smartpqi. The PCI_MEM macros don't require a physical/absolute address in FreeBSD, but it looks like the calling code might be somewhat portable to other OS's that do require this. Therefore, set the variables to __unused instead of removing the code entirely.

The branch stable/13 has been updated by imp:

    Fix "set but not used" in smartpqi.  The PCI_MEM macros don't require a
    physical/absolute address in FreeBSD, but it looks like the calling
    code might be somewhat portable to other OS's that do require this.
    Therefore, set the variables to __unused instead of removing the code
    entirely.
