With clang 15, the following -Werror warning is produced: sys/dev/mthca/mthca_cmd.c:662:23: error: variable 'tc' set but not used [-Werror,-Wunused-but-set-variable] int ts __unused = 0, tc = 0; ^ The 'ts' and 'tc' variables are eventually used only in mthca_dbg() macros, if CONFIG_INFINIBAND_MTHCA_DEBUG is defined. Ensure 'ts' and 'tc' are only declared and used when CONFIG_INFINIBAND_MTHCA_DEBUG is defined. MFC after: 3 days
