[PATCH v2] [media] s5p-jpeg: Only build suspend/resume for PM

From: Thierry Reding
Date: Tue Oct 14 2014 - 06:10:48 EST


From: Thierry Reding <treding@xxxxxxxxxx>

If power management is disabled these function become unused, so there
is no reason to build them. This fixes a couple of build warnings when
PM(_SLEEP,_RUNTIME) is not enabled.
