Subject: perf/marvell_cn10k: Fix unused variable warning when W=1 and
CONFIG_OF=n
Git-commit: 8c0c56879d067ad1e68c0aeeecc7d5f57bac3ffd
Patch-mainline: v5.18-rc1
References: jsc#PED-1765
The kbuild helpfully reports that the Marvell CN10K TAD PMU driver emits
a warning when building with W=1 and CONFIG_OF=n:
| >> drivers/perf/marvell_cn10k_tad_pmu.c:371:34: warning: unused variable 'tad_pmu_of_match' [-Wunused-const-variable]
static const struct of_device_id tad_pmu_of_match[] = {
Guard the match table with CONFIG_OF to squash the warning.
