6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Raviteja Laggyshetty <quic_rlaggysh@xxxxxxxxxxx>
[ Upstream commit 05123e3299dd6aa02508469b303262338c2a661c ]
Return -EPROBE_DEFER from interconnect provider incase probe defer is
received from devm_clk_bulk_get_all(). This would help in reattempting
the inteconnect driver probe, once the required QoS clocks are
available.
