Subject: RFC: a failing pm_runtime_get increases the refcnt?

Hi Linux-PM,

both in the I2C subsystem and also for Renesas drivers I maintain, I am
starting to get boilerplate patches doing some pm_runtime_put_* variant
because a failing pm_runtime_get is supposed to increase the ref
counters? Really? This feels wrong and unintuitive to me. I expect there
has been a discussion around it but I couldn't find it. I wonder why we
don't fix the code where the incremented refcount is expected for some
reason.

Can I have some pointers please?

Thanks,

   Wolfram
