commit 91dc90fdb8b8199519a3aac9c46a433b02223c5b upstream.
Commit 6240aaad75e1 was supposed to drop the reference count to the OPP,
instead it avoided more stuff if the OPP isn't found. This isn't
entirely correct. We already have a frequency value available, we just
couldn't align it with an OPP in case of IS_ERR(opp).
Lets continue with updating thermal pressure, etc, even if we aren't
able to find an OPP here.
This fixes warning generated by the 'smatch' tool.
