6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>
commit b17155133391d7f6dd18d3fb94a7d492fdec18fa upstream.
The rpm_requests device nodes have the compatible node. As such the
rpmsg core uses OF modalias instead of a native rpmsg modalias. Thus if
smd-rpm is built as a module, it doesn't get autoloaded for the device.
Revert the commit bcabe1e09135 ("soc: qcom: smd-rpm: Match rpmsg channel
instead of compatible")
