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. Suggested-by: Bjorn Andersson <andersson@kernel.org> Signed-off-by: Raviteja Laggyshetty <quic_rlaggysh@quicinc.com> --- Changes in v2: - Removed the qos_clk_required rename change and posted it as separate patch. - As suggested, dev_err_probe is used for reporting the probe defer error message. --- drivers/interconnect/qcom/icc-rpmh.c | 3 +++ 1 file changed, 3 insertions(+)
