Hmm, perhaps I got a little carried away implementing Mark's recommendation in 88b63a82c84e ("perf/arm-cmn: Fix CCLA register offset"), and the HN-P/CCLA_RNI case could have been left as it was using CMN_HNP_PMU_EVENT_SEL. Either way, I think it's beneficial to keep both definitions next to each other, so that it's at least visible from the code alone (without having to resort to the CMN documentation) that the two node types do have equivalent offsets and that combined case is still not a bug.

By reading the code, I found the marco CMN_HNP_PMU_EVENT_SEL is never referenced in the code. Just remove it. Signed-off-by: Ba Jing <bajing@cmss.chinamobile.com> --- drivers/perf/arm-cmn.c | 1 - 1 file changed, 1 deletion(-)
