i've encountered a bug in regulator between 5.3-rc5 and next-20190822

i build for bananapi-r2/mt7623 using this branch (includes next-patches):


and noticed that switch does not came up

priv->core_pwr = devm_regulator_get(&mdiodev->dev, "core"); returns 517

located here:

#define EPROBE_DEFER 517/* Driver requests probe retry */


seems of_find_regulator_by_node(node); is failing here, but i see the dts-node (mt6323_vpa_reg: buck_vpa) in /sys/firmware/devicetree/...

tried without next-patches and switch came up including dsa-ports.

i found no commit yet which breaks the regulator-setup

any idea about this?

regards Frank
