This was an issue on at least some Nvidia boards. The Qualcomm platforms are running into trouble because the qcom_smd driver is broken and apparently nobody checks -next works for their boards since they only noticed after -rc1 in spite of the change having been in -next for a good few weeks. You need at least "regulator: qcom_smd: add list_voltage callback" and "regulator: qcom_smd: add regulator ops for pm8941 lnldo" from my tree which I didn't send to Linus yet since we only got them in at the end of last week. I think that's probably OK for v4.6 TBH, the platform is fairly incomplete upstream and the original patch fixes issues for other systems. > So since this patch made it to stable, commit a21513742308 ("regulator: Fix > deadlock during regulator registration") [0] should also be included.
