6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuquan Wang <wangyuquan1236@xxxxxxxxxxxxxx>
[ Upstream commit b7c59b038c656214f56432867056997c2e0fc268 ]
The dev_dbg info for Clear Event Records mailbox command would report
the handle of the next record to clear not the current one.
This was because the index 'i' had incremented before printing the
current handle value.
Fixes: 6ebe28f9ec72 ("cxl/mem: Read, trace, and clear events on driver load")
