Subject: [PATCH 3.16 131/132] media: poseidon: Depend on PM_RUNTIME

3.16.74-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@...adent.org.uk>

This is a stable-only patch as the driver has been removed upstream.

Commit c2b71462d294 "USB: core: Fix bug caused by duplicate interface
PM usage counter" switched USB to using only the standard runtime PM
mechanism.  In my backport I changed poseidon to read the runtime PM
counter, but that means it now needs to depend on PM_RUNTIME.
