Initialize the managed OPP pointer at declaration rather than
assigning it in a separate statement.
This avoids a checkpatch warning about a potentially uninitialized
managed pointer.
Signed-off-by: Hungyu Lin <dennylin0707@gmail.com>

Changes in v2:
- Initialize the managed pointer directly at declaration as suggested
by Dmitry Baryshkov.
