[PATCH 0/4] coresight: Patches for v5.13

[Mathieu Poirier]

Hi Greg,

These are the coresight patches I'd like you to consider for
the v5.13 cycle.  There is only 4, the other ones will go
go through Marc's kvmarm tree as previously agreed.

I may have another (big) set coming later this week or early
next week but it may be on the late side for this much code.
We'll see when we get there.

Thanks,
Mathieu

[PATCH 2/4] coresight: etm: perf: Make symbol 'format_attr_contextid' static

[Mathieu Poirier]

From: Wei Yongjun <weiyongjun1@huawei.com>

The sparse tool complains as follows:

drivers/hwtracing/coresight/coresight-etm-perf.c:61:25: warning:
 symbol 'format_attr_contextid' was not declared. Should it be static?

This symbol is not used outside of coresight-etm-perf.c, so this
commit marks it static.
