I did rebase the series (which required some rebase related changes for some) on
coresight next i.e with the following commit as HEAD.
a4f3057d19ff ("coresight-tpda: Change qcom,dsb-element-size to qcom,dsb-elem-bits")
Although did not see any warning either with = m or = y based coresight options.
Is there any other particular config which needs to be enabled for these warnings
to come up ?
