[Mesa-dev] [PATCH 09/12] intel: aubinator: mark *res as MAYBE_UNUSED in get_ppgtt_batch_bo

Only used, when asserts are enabled.

Fixes an unused-variable warning with GCC 8:
 ../../../src/intel/tools/aubinator.c: In function 'get_ppgtt_batch_bo':
 ../../../src/intel/tools/aubinator.c:383:13: warning: unused variable 'res' [-Wunused-variable]
        void *res = mmap((uint8_t *)bo.map + (page - bo.addr), 4096, PROT_READ,
              ^~~
