Hi Kevin, thanks for trying this. I got the same with v4.5-rc2, but
this is expected as it depends on the another recently merged patch
in linux-next. Perhaps I should have mentioned this in the commit
message.

Anyway, just checked with next-20160205 and it works for me - tested
with 3 different cards. Not sure why it does not work for you.
Could you please check if you have the following patch in your tree:

4fbdc4e6adbc arm64: dts: apq8016-sbc: add regulators support
$ git tag --contains 4fbdc4e6adbc
next-20160201
next-20160202
next-20160203
next-20160204
next-20160205

BR,
