IB/hfi1: Fix sdma_event_names[] build warning
sdma_event_names[] is only used within CONFIG_SDMA_VERBOSITY ifdefs, so when CONFIG_SDMA_VERBOSITY is disabled, it results in the following 0-day build warning: >> drivers/infiniband/hw/hfi1/sdma.c:137:27: warning: 'sdma_event_names' >> defined but not used [-Wunused-const-variable=] static const char * const sdma_event_names[] = { ^~~~~~~~~~~~~~~~ This occurs on the following compiler: compiler: gcc-6 (Debian 6.1.1-1) 6.1.1 20160430 For more information check: https://lists.01.org/pipermail/kbuild-all/2016-May/020060.html Fix this warning by defining sdma_event_name[] only within the CONFIG_SDMA_VERBOSITY ifdefs.
