You shouldn't just be ignoring errors here, though there are deployment difficulties with making sure a stub regulator is provided. These should be getting easier after the next merge window, the stubs will be being tweaked slightly to have an "assume it's there" option even when
Oh, really, could you show me the patch, I wish to take a look :)
No patch quite yet - the basic idea is that for plain regulator_get() you'll only ever get -EPROBE_DEFER as an error, not -ENODEV. If the regulator is missing in the DT we assume it's there and provide a dummy if the DT doesn't hook it up. If the consumer genuinely wants to see if a supply might not be wired up it should use regulator_get_optional() which is in -next at the minute. -------------- next part -------------- A non-text attachment was scrubbed...
